• 【SUPER BRIGHT】Each 1157 switchback led bulb equipped with 16 pieces 3030 SMD chips, 360° lighting, no dark spots or shadow areas, protected with HD glass lens for stronger light penetration and maximum light output.

• 【MULTI APPLICATIONS】White for DRL or parking lights; Amber yellow for turn signal lights. The 1157 Led bulb flashes "amber-off-amber-off" instead of "amber-white-amber-white" which makes them easier to see. (Most 1157 switchback led turn signals on the market flash amber-white-amber-white)

• 【35,000 HOURS LIFESPAN】9V to 18V wide-range voltage design, the 1157 switchback led turn signal bulb adopts a built-in constant current IC driver and high-quality aluminum material for lower power consumption and long lifespan.

• 【INSTALLED IN MINUTES】Non-polarity design, plug, and play easy installation. The 1157 led bulb fit for 1157 1157A 1157NA 1157ALL 1157LL 1157ST 2057 2057A 2357 2357A 2357NA 7528 BAY15D P21/5W 1016 1034 1034A 1034LL 1034NA 1035 1178 1196 198 198LL 198NA 2397 2397LL 3496 etc.

• Note: 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

• Much Easier to See: The 1157 Switchback LED turn signal light bulbs flash "amber-off-amber-off" instead of "amber-white-amber-white".
• Fit for: 1157 1157A 1157NA 1157ALL 1157LL 1157ST 2057 2057A 2357 2357A 2357NA 7528 BAY15D P21/5W 1016 1034 1034A 1034LL 1034NA 1035 1178 1196 198 198LL 198NA 2397 2397LL 3496 etc.
