3157 Switchback LED Front Turn Signal Bulbs White Amber | Built in Resistors, Dual Color, No hyperflash

Why 3157 Switchback LEDs Are the Best Turn Signal Light Bulbs 

Our 3157 Switchback LED bulbs transform your vehicle's front turn signals with plug-and-play simplicity. Installation takes just 10 minutes with no splicing or complex wiring needed for 99% of vehicles.

These premium 24W 1200LM dual-color LEDs feature innovative engineering that sets them apart. Unlike competitors, we've placed built-in resistors only on the turn signal filament, not both circuits. This strategic design prevents excessive heat exposure from housing melt and component failure while eliminating hyperflash and error codes. We've added a smart cooling fan that activates only when the high filament engages, extending the 3157 LED bulbs lifespan.

Each switchback LED turn signal light contains 54 high-performance SMD LED chips arranged for 360-degree illumination - 18 for a crisp 6000K white color (parking light /daytime running light mode) and 36 for brilliant 3500K amber (turn signal mode). The result? White running lights that instantly switch to intensely bright amber when signaling, then back to white when complete. 

These signature switchback lights mimic the sophisticated look of luxury vehicles while providing better functionality over standard halogen bulbs. They activate instantly and create a distinctive lighting pattern that improves both style and safety.

Note: Your socket must have three wires for proper dual-color functionality. Two-wire sockets will only display one color. Most 3157 applications use 3-wire systems compatible with both white and amber operations.
