Best Performance in Industry. Our Ultra Bright 24W 1200LM 3157 Switchback W/ Built-in Resistors Dual Color LED DRL/ Parking light Turn Signal Light Bulbs White/Amber No hyper flash (2 Pieces) are dual-colored type LED lights that cover 360 degrees to provide maximum output. Unlike other brands, with resistors on both the amber and white filament, we created a CANBUS LED switchback that only has a built-in resistor on the turn signal filament. Having a resistor on both the amber and white filament will lead to melting the housing or the LED falling apart in the housing. Our design protects the LED from being exposed to constant heat eliminating this issue. This assures no hyper-flashing or error codes. We even took it one step farther, to ensure the longevity of the bulbs, by adding a cooling fan. The fan only turns on when the high filament is engaged, to reduce heat when the resistor is on.  Our LED is designed to replace the factory incandescent bulb without the need to add extra resistors or parts.

Best-In-Class Brightness. Each 3157 Switchback LED is equipped with 54 SMD LEDs Dual Colored type LED lights 360 degrees to provide the max output. 18 LEDs are for White, and 36 LEDs are for Amber. Light up 6000K Pure White for parking or daytime running lights (DRL), and switch over, so your turn signals blink a lot brighter than the stock incandescent bulb with our 3500K Amber.

You’ll be hard-pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these bulbs feature an impressive 54 dual-color LED chip design.

What Are Switchback LED Lights? Seen on most high-end luxury vehicles, LED stands for Light-emitting Diodes. LEDs shine brighter than any halogen bulb. LEDs create light instantly! Switchback LED lights take it to the next level. With dual filaments that allow you to change between two light colors/shades, they will enable you to switch from low-intensity parking lights to high-intensity lights.

3157 Switchback LED bulbs are a unique way to upgrade your turn signal! In a dual-filament socket, they will light up with white color as the low-filament running light, and switch to bright amber any time you hit the turn signal. When you switch the turn signal off, they'll "switch back" to white again.

Please Note: For a switchback to work correctly, your socket must have 3 wires going to it. If your socket has only 2 wires then your vehicle will not show two color white and amber. It will only show 1. Most 3157 applications have 3 wires which will allow both colors white and amber to work.
