Switchback LED Light Bulbs for 3157/3156 Turn Signals and DRLs

The 3157 dual-contact, dual-function bulb is equipped with 20 LEDs (5630 SMD) and can produce up to 400 lumens at 6500-8000K. It is constructed with a built-in intelligent IC driver and aviation aluminum material to ensure better performance. This energy-efficient bulb has a lifespan of 50,000 hours on cars, trucks, SUVs, or vans, which is 45 times longer than incandescent bulbs.

Installation is easy with a simple plug-and-play process - just twist to lock in place. However, it is important to note that when using LED bulbs for turn signal lights, a 50W 6-Ohm load resistor or decoder set may be required to avoid hyper flash or bulb malfunction.

The 3157 Socket is compatible with various stock bulbs including 3047, 3057, 3057A, 3155, 3157, 3157A, 3157NA, 3357, 3357A, 3454NA, 3457, 3457A, 3457NA, 3757A, 4057, 4114, 4157, 4157NA, 5702A, and 5702AK. It can be used as vehicle tail lights, brake lights, reverse lights, turn signals, and side marker lights.

This versatile bulb can light up Xenon White for parking lights or daytime running lights, and it can also light up Amber for turn signal lights. With its long lifespan and multiple applications, the 3157 LED bulb is a reliable and energy-efficient choice for vehicle lighting needs.
