3G15A-T15-W LED Back-Up Light Extremely Bright Aluminum PCB

The 3G15A-T15-W is a dedicated T15 LED back-up light designed to deliver strong illumination in a compact footprint. It uses high-efficiency 2835 SMD LEDs mounted on an aluminum substrate to provide a bright, clean beam that makes reversing safer and more comfortable. With a working current of 350±20 mA and a 9–16V DC input range, this bulb integrates smoothly with standard passenger vehicle electrical systems, offering a simple plug-and-play upgrade from conventional halogen lamps.

Bright Output for Clear Reversing

This T15 LED bulb is engineered to provide a noticeably brighter output than traditional halogen reverse lights. The focused emitters project a concentrated white beam that clearly defines obstacles, lane markings, and garage walls when backing up. Around 800 lumens of light are directed rearward, giving drivers better awareness of their surroundings in dark alleys, parking structures, or unlit driveways. The strong output also makes the vehicle more visible to other road users, helping to reduce the risk of minor collisions during low-speed maneuvers.

High-Efficiency 2835 SMD LED Technology

At the core of the 3G15A-T15-W are 2835 SMD LEDs chosen for their balance of brightness, efficiency, and reliability. These surface-mount devices offer a wide light-emitting surface, which helps create a uniform, glare-controlled beam. Compared with older LED packages, 2835 chips can achieve higher luminous flux at a given drive current, meaning more usable light for the same electrical load. Their flat profile also allows the light engine to sit close to the optical center of the bulb, improving how well the beam matches the original lamp housing.

Aluminum PCB for Strong Heat Dissipation

Thermal management is critical in compact LED bulbs, and this model addresses it with an aluminum PCB. The metal-core board acts as a heat spreader, pulling heat away from the LED junction and distributing it along the body of the bulb. This helps keep operating temperatures under control during extended reversing or when the bulb is used as a rear fog light in bad weather. Better heat dissipation means lower lumen decay over time, more stable color, and a longer effective service life compared with designs that rely on standard FR-4 circuit boards.

Compact Form Factor with Optimized Heat Sink

The 3G15A-T15-W retains a slim, compact profile that fits easily into existing T15 housings. The body length is about 29 mm, making it suitable for tight lamp compartments where space around the socket is limited. A structured outer shell functions as a passive heat sink, increasing surface area so that air can remove heat efficiently as the vehicle moves. The mechanical design keeps weight low while maintaining rigidity, reducing stress on the socket during vibration and everyday driving.

Clean White Beam and Improved Rear Visibility

The combination of modern LEDs and a clear lens produces a sharp, clean white beam. This helps reveal road textures, curbs, and objects behind the vehicle more clearly than the soft, yellowish light from many halogen bulbs. The defined hotspot assists drivers in judging distance, while the surrounding spill light illuminates a wider area around the vehicle. The result is a more confident reversing experience, particularly in confined spaces where precise maneuvering is required.

Stable Electrical Performance on 9–16V Systems

Designed for typical automotive electrical environments, the bulb operates across a 9–16V DC range. The 350±20 mA drive current keeps brightness consistent even as system voltage fluctuates with engine load or battery condition. This makes the 3G15A-T15-W suitable for vehicles that see frequent stop-and-go use, cold starts, or short trips where voltage may vary. The electrical design aims to minimize flicker and maintain stable performance without requiring additional resistors for most applications.

Simple Plug-and-Play Replacement

Installation is straightforward thanks to the T15 (W16W) wedge base. There is no need for rewiring or modification; the bulb simply inserts into the existing socket in place of the original lamp. Its compact dimensions mean it can be used in a wide range of vehicles equipped with T15 back-up or rear fog light positions. For workshops and distributors, this simplicity translates into shorter installation times and fewer compatibility questions, making the 3G15A-T15-W an efficient upgrade choice.

Versatile Use as Back-Up or Rear Fog Light

Although optimized for reversing lights, the bulb can also be used as a rear fog light in suitable housings, where regulations allow. The strong, concentrated output cuts through mist, light rain, or dust, making the vehicle easier to spot from behind. This dual-use capability allows stocking a single model that covers both functions in many applications, simplifying inventory while still delivering a noticeable performance improvement over standard bulbs.

Overall, the 3G15A-T15-W combines high-efficiency 2835 SMD LEDs, an aluminum PCB, and a compact thermal design to deliver bright, reliable illumination in a familiar T15 package. It is a practical and effective way to upgrade the safety and appearance of the rear lighting on modern vehicles.
