500% Brighter Than Traditional Halogen Bulbs：With the lens boosting light utilization, the 3157 led bulb emits 6000K cool white light—500% brighter than traditional halogen bulbs. 360°full-angle light output with 66 high-precision SMD chips provides clear and bright illumination, enhancing visibility on the road and improving driving safety at night or in bad weather.

Unique Lens Cover Design：Unlike most 3157 LED bulbs without lenses, ours features a custom optical lens. It delivers 95% high light transmittance, ensuring light is fully and evenly distributed. The lens diffuses harsh light rays into soft glow, which won’t dazzle other drivers. It provides a comfortable visual experience for you while protecting the safety of oncoming or following vehicles.

5 Mins Easy Installation：Non-polarity design fits US standard and CK sockets, perfectly fits 3157, 3156, 3056 3057 3757 4157 4156 3457 3047 4057 4114 socket types. Suitable for car backup lights, reverse lights, tail lights, brake 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 these 3156 led 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.
