500% Brighter Than Halogen Bulbs: With the lens enhancing light utilization, this 3157 led red bulb emits super bright red light—500% brighter than traditional halogen bulbs. 66 high-precision SMD chips deliver 360° full-angle light output. The red light features strong warning performance and excellent penetration, allowing following vehicles to quickly capture signals such as braking and position indication, significantly improving driving safety in low-visibility conditions like nights and rainy days.

Unique Lens Cover Design: Unlike most red 3157 LED bulbs without lenses, this product features a custom optical lens with a high light transmittance of 95%, ensuring full and even light distribution. The lens diffuses harsh red light into a soft and eye-catching glow, preventing glare to following vehicles from direct strong light. It not only guarantees clear and intuitive warning signals but also provides a comfortable visual experience for other vehicles on the road.

5 Mins Easy Installation: Non-polarity design fits US standard and CK sockets, perfectly fits 3157, 3157R, 3156, 3156R, 3057, 3057R, 4157, 4157R, 4156, 4156R, 3757, 3757R, 3457, 3457R, 3047, 3057R, 4057, 4057R, 4114, 4114R socket types. Suitable for car tail lights, brake lights, stop lights, backup lights, reverse lights, turn signal lights, parking lights, daytime running lights, and so on. Even beginners can finish installation in 5 minutes by directly replacing the original halogen bulb. (Please confirm your car’s bulb model before purchasing).

Durable & Long-Lasting: Made of aviation-grade aluminum body and scratch-resistant optical lens, accelerating heat conduction and diffusion for a significant boost in heat dissipation efficiency, preventing premature aging of LED chips caused by overheating. The service life of 3156 led red bulb is up to 30,000 hours, reducing the frequency of bulb replacement.

Stable & Excellent Performance: Built-in EMC module, which has passed strict electromagnetic radiation tests. It will not interfere with on-board electronic devices such as car navigation, radio, and backup camera during operation, avoiding problems such as signal noise and screen flicker that affect the driving experience. Some sensitive vehicles may meet canbus issus such as bulbs flicker, hyper flash or error warning on dashboard, etc, load resistors will be helpful to solve these issues.
