LED and custom motorcycle tail lights: the guide to choosing the right rear lighting
On a custom, café racer, scrambler, or bobber motorcycle, the tail light is not just an accessory. It is both the final visual signature of your build and the safety element that other road users constantly see behind you. A poorly chosen tail light can ruin the style or, worse, lead to questionable compliance during technical inspections. A well-chosen tail light offers a sharp silhouette, optimal visibility day and night, and the peace of mind of an E-mark or ECE approved product. At Blackpines, we have selected the most advanced references on the market for you: from the ultra-compact LED micro-light by Kellermann or Motogadget, to integrated 3-in-1 kits that combine position light, brake light, and turn signals in a single compact housing. Here's everything you need to know to make the right choice.
Motorcycle tail light: the different types available
The custom motorcycle tail light market has expanded considerably in recent years, particularly driven by SMD LED technology, which has drastically reduced the size of optics while improving their brightness. Today, several main families can be distinguished.
The round tail light, Bates or Bullet style, remains a timeless classic for café racer and bobber builds with a vintage look. Compact, often made of aluminum or painted metal, it attaches directly to the rear fender via one or two anchor points. Models like the Reprobate LED tail light from Motone Customsprecisely adopt this code, combining it with modern SMD LED technology, with a glossy black or polished finish that perfectly matches café racer and scrambler aesthetics. E-Mark approved, it can be legally ridden on the road.
Sleek "low profile" or "flat" design tail lights are particularly suited for builds where maximum rear volume reduction is desired. The Mo.blaze Tens 2 by Motogadgetis the perfect example: a remarkably thin LED strip that integrates position light and brake light into an almost invisible profile, leaving only a thin and sharp light signature. This minimalist approach is particularly consistent with stripped-down trackers, flat trackers, and streetfighter builds.
3-in-1 tail lights with integrated turn signals now represent the most complete solution for those who want to simplify their rear wiring while gaining visual coherence. By combining position light, brake light, and turn signals in a single approved device, they eliminate the need for separate rear turn signals and significantly lighten the motorcycle's silhouette. The Mo.Blaze Tens 3 by Motogadgetis one of the most advanced references available at Blackpines in this regard. Certified compliant with ECE R148 standards, it is the preferred choice of demanding builders.
Finally, premium multi-function tail lights like the Mo.Rear by Motogadgetrepresent the ultimate in the category. A true all-in-one module, it integrates brake light, position light, turn signals, and license plate illumination into a high-finish machined housing, compatible with the entire Motogadget electronic ecosystem. An investment geared towards high-end custom projects.
Approved motorcycle tail light: why is it essential?
The question of approval is central when a tail light is intended for use on open roads. In France, as in the entire European Union, a tail light must meet precise technical standards to be legal. The reference standard is E-Mark, which certifies the product's conformity with European directives on lighting and signaling. For the most recent products, ECE R148 applies to grouped, combined, or mutually incorporated luminous signaling lights. The Motone Customs ICON 3-in-1, for example, is explicitly certified ECE R148, a guarantee that the product has been laboratory tested and meets all visibility, light intensity, and heat dissipation requirements imposed by regulations.
In practical terms, riding with an unapproved tail light can result in a fine during a check and rejection at a technical inspection. More seriously, in the event of an accident, non-compliant lighting can impact insurance coverage. Approval is therefore not an administrative detail: it is a guarantee of legal and real safety.
At Blackpines, the tail lights offered by brands such as Motogadget, Kellermann, Motone Customs, Highsider, and Daytona are systematically approved for legal road use in Europe. For more accessible references in our catalog, we specify the approval status in each product sheet so you can make an informed choice.
LED motorcycle tail light: the advantages of SMD LED technology
Almost all tail lights in our selection today are based on LED technology, specifically SMD (Surface Mounted Device) LEDs. Compared to a conventional incandescent bulb, an SMD LED offers decisive advantages in the context of motorcycle use.
In terms of visibility, an LED's response is almost instantaneous, on the order of a few milliseconds compared to several hundred milliseconds for a conventional bulb. In an emergency, this reaction time translates into a shorter braking distance for the following vehicle. The brightness of SMD LEDs is also much higher than that of an incandescent bulb with equivalent consumption: they consume, on average, five to ten times less energy for the same or greater light output.
From a durability perspective, an SMD LED has a lifespan of approximately 30,000 to 50,000 hours, compared to 1,000 to 2,000 hours for an incandescent bulb. On a motorcycle, this practically means a lifetime of the vehicle, eliminating the need for any bulb changes. This robustness is also reinforced by the absence of a filament, an inherently fragile element particularly sensitive to vibrations inherent in motorcycle use.
Finally, the miniaturization made possible by SMD LEDs is what has made ultra-compact tail lights like those from Kellermann or Motogadget possible. The Kellermann Atto® RB, for example, is one of the smallest LED tail and brake lights in the world approved for road use. It fits in the palm of your hand yet delivers ample light output to ensure optimal visibility, day and night.
Which tail light to choose according to your motorcycle's style?
The choice of a tail light is inseparable from the overall aesthetic of your build. An overly massive or disproportionate light can disrupt the harmony of a carefully crafted silhouette. Here are some guidelines by motorcycle style.
For a café racer, the dominant trend is purification. A compact tail light with low mounting on the fender, an aluminum housing, and a discreet round or oval optic is preferred. The Motone Customs Reprobate, Bel Air, Big Fin, or Lecterare all variations that adhere to this logic. Each offers a slightly different visual imprint; the Reprobate plays on pure retro, the Lecter displays a more contemporary character, while ensuring position and stop functions.
For a scrambler or tracker, a visually more assertive light can be considered, possibly with a smoked lens that plays on the material effect. Motogadget or Highsider's 3-in-1 solutions are perfectly suited to these styles, as they eliminate separate turn signals and create a look that is both technical and clean.
For a bobber or American-style custom, round shapes and chrome or matte black finishes dominate. The Bullet Chopper tail lightor the Sportster LED tail lightfall within this tradition. A "Bullet" or "Bates style" tail light on a bobber creates immediate visual coherence that speaks for itself.
For specific motorcycles such as Royal Enfield 650, Triumph Bonneville, Street Twin, Scrambler, or T100/T120, dedicated kits exist and simplify installation. The Bonvent mini tail light kit for Royal Enfield 650or the Motone Customs Eldorado Tail Tidy Kit for Triumphare examples of complete kits that include the light, license plate bracket, and sometimes turn signals, prepared to adapt without modification to the original wiring harness.
Tail light and turn signals: key installation considerations
Replacing an original tail light with an aftermarket model is an accessible operation, provided a few essential rules are followed.
The first point concerns electrical compatibility with LEDs. Most modern motorcycles are designed with 10W incandescent turn signal bulbs. The turn signal relay is calibrated for this resistance. When replacing turn signals or a 3-in-1 light with LEDs, the electrical consumption is much lower, which can cause "hyperflashing": the turn signals flash too quickly, or not at all. On Triumph Twins up to 2015 and on some Royal Enfield models, it is necessary to replace the original relay with an LED-compatible relay, available in our turn signalssection. On liquid-cooled Triumphs from 2016 onwards, the adjustment can be made via the dashboard. Inquire before purchase or contact our customer service.
The second point concerns license plate illumination. Not all tail lights include it. The Motone Customs Reprobate light, for example, does not include license plate illumination, so it will need to be supplemented with a separate license plate light available in our catalog. Other models like the Motone Bel Air or Big Fin integrate it natively. Be sure to check this in the product sheet before ordering.
The third point concerns the mounting bracket. A universal tail light fits the vast majority of motorcycles but may sometimes require slight drilling or the use of an intermediate bracket depending on the configuration of the original fender. Read the mounting specifications carefully and do not hesitate to contact us with any compatibility questions.
Complete your lighting: headlights, auxiliary lights, and turn signals
The tail light is not chosen independently of the rest of your motorcycle's lighting. For optimal visual and technical coherence, all lighting signals—front, side, and rear—deserve comprehensive consideration. Discover our other collections dedicated to motorcycle lighting:

FAQ — Motorcycle Tail Lights: Most Frequently Asked Questions
What is a 3-in-1 tail light?
A 3-in-1 tail light is a device that combines three distinct functions in a single housing: the position light (rear running light), the brake light, and the turn signal. This solution eliminates separate rear turn signals for a cleaner look and simplified wiring. To be legal on the road, it must be approved according to ECE R148 standards or bear the E-Mark.
How do I know if a tail light is approved for road use in France?
A tail light approved for the European Union bears the E-Mark, sometimes noted "E" followed by a country number (e.g., E2 for France). Products compliant with ECE R148 explicitly state this in their technical specifications. In our Blackpines product sheets, this status is systematically specified. In the absence of an E-mark, the light cannot be legally used on public roads and may result in rejection during technical inspection.
Do I need to install a resistor or change the relay when installing an LED light on an older motorcycle?
In most cases, yes. A classic turn signal relay is calibrated for the electrical resistance of an incandescent bulb (typically 10W). Since LEDs consume much less, the relay detects a lack of load and causes hyperflashing (too rapid flashing) or no flashing at all. The simplest solution is to replace the relay with an LED-compatible electronic relay, available in our shop. On some recent Triumph and Ducati models, this adjustment can be made directly from the dashboard. We have written a mounting guide available on our blog: Simple and Effective Guide to Mounting LED Motorcycle Turn Signals
Which tail light should I choose for a café racer?
For a café racer, the ideal tail light is compact, discreet, and has an aluminum housing. Motone Customs references (Reprobate, Bel Air, Cuda, Eldorado, Big Fin) are particularly suitable for this use. They combine SMD LED technology, refined finish, and road approval. The Kellermann Atto® RB is also an excellent choice for its tiny size and exceptional brightness. For even more stripped-down Café Racers, the Motogadget Mo.blaze Tens 2 offers an almost invisible LED strip that disappears into the motorcycle's silhouette.
Does a motorcycle tail light always include license plate illumination?
Not systematically. Some models natively integrate license plate illumination (like the Motone Customs Bel Air, Big Fin, or Cuda, which combine position, stop, and license plate illumination), while others do not (like the Motone Reprobate). In this case, a separate license plate light is necessary. Always check this in the product sheet, as the absence of license plate illumination constitutes a traffic violation.
Can a universal tail light be mounted on any motorcycle?
Most "universal" tail lights fit a wide variety of motorcycles. However, ease of installation depends on the fender configuration and original wiring. On motorcycles like the Triumph Bonneville, Royal Enfield Interceptor 650, or BMW R nineT, dedicated kits or wiring harness adapters ensure installation without modifying the original wiring. This is a preferred solution to preserve the motorcycle's electrical integrity. Consult product sheets or our customer service for any compatibility doubts.
What is the difference between a position light and a brake light?
The position light (or rear running light) is constantly illuminated when the ignition is on, with low light intensity. It signals the presence of the motorcycle. The brake light illuminates with higher intensity when the front or rear brakes are applied, to warn following vehicles of deceleration. Regulations require the brake light to be significantly brighter than the position light to be clearly identifiable. SMD LEDs easily achieve this intensity differentiation while consuming very little energy.
How much does a good LED motorcycle tail light cost?
The LED tail lights in our selection cover a wide price range, suitable for all budgets and requirements. Entry-level models start around €13 to €30 for universal references like classic round or Bullet lights. Mid-range, higher-quality references, such as Motone Customs Bel Air, Big Fin, Cuda, or D-TAIL Daytona lights, are between €60 and €100. High-end premium lights from Kellermann, Motogadget, or Highsider, or integrated 3-in-1 kits, range from €100 to €300 for the most advanced versions. The price reflects manufacturing quality, optical precision, miniaturization, and the level of approval.
