SEALIGHT 3157 Switchback LED, 2025 Latest 3157 LED Bulb Dual Color Amber Yellow/White 3156 3457 4157 T25 Lamps with HD Len & Extra Resistor for Turn Signal/DRL/Parking Lights, 34-SMD Chipset, 2PCs

【White ＆ Amber Switchback】White for parking lights or daytime running lights (DRL lights) while light up amber yellow for turn signal lights. 3157/3156 turn signal flashes "amber-off-amber-off" instead of " amber-white-amber-white", much easier to see from a distance. ( Most switchback bulbs in the market flash amber-white-amber-white ).

【360 Degree Clear Beam】: Each 3157 3156 bulb is equipped with 34 high-power 3030 chipsets, including 13 SMD white + 21 SMD amber chips, with a power of 5W, low power consumption but high light output. Equipped with HD glass lens, it can increase the intensity and range of light speed, with stronger light penetration and 150% larger visualization.

【 400% Faster Heat Dissipation】2025 Latest 3157a led bulb adopts three major designs to improve heat dissipation: ① Upgraded 6063 aluminum alloy housing for superior heat dissipation ② Hollow thermal design for enhanced airflow ③ Intelligent IC chip cooling system for rapid cooling, achieving maximum light output and better heat dissipation, with a service life of up to 7 years.

【5-Min Quick Installation】1:1 base design, non-polarity, plug and play, even if you have no previous experience, you can install the 3157 led bulbs in 5 minutes. Used for replacing the stock dual-function halogen or damaged dim 3156, 3157, 3157A, 3057, 3155, 3157NA, 3357, 3457, 3457A, 4057, 4114, 4157 turn signals, parking lights, and daytime running lights.

【Kind Tips】: These will only work for dual function lights that have both the parking/city light and turn signal function in one bulb. The 50w 6ohm load resistor or flasher relay may be needed to prevent the hyper flash or the bulb does not blink, we have included the resistors in the package in case you need it.
