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 future to ensure the longevity of the bulbs by adding a cooling fan. The fan only turns on when the turn signal is on, 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 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 mush have 3 wires going to it. If your socket has only 2 wires than 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.
Difficulty Level: Beginner - Simple Installation for anyone.
Installation time is approximately 10 minutes. There is no need for slicing or complicated wiring. This light is a plug-n-play installation and operation.

Awesome lights very bright and work as they said no hyper flash!
LED from underground has made the difference with my truck lights, and I haven't had any problems with the truck hipper flashing.
I wish I'd seen these videos before I decided to be Mr Fixit. 2 minutes to install in my 2017 Grand Cherokee Altitude. Turned the signals on and about had a stroke because they hyper-flashed. Turned them off, started the engine and let it run for a minute. Turned the signals back on, the fault cleared and they work perfect. Love these switchbacks
I replaced a 3157 switchback w/c is hyperflashing with this and oh Boy it was more than 1200 lumens bright! NOW i dont have hyperflash , its blinking normally plus a DRL thats like a fog light , Thank you so much UL florida and Danny APPRECIATE IT!!!
I had leds with resistors to prevent hyperplasia and other problems that you get with a 2011 Ram 1500. But when I install these it was like night and day. So bright and they switch back and forth with no problem. My truck rolls down the road as bright as a full moon. No more resistors or DST popping up for some reason due to led lights.
Thanks Underground Lighting and Danny your the best.
Installed on 2010 F150 in front turn signal/parking light and they work flawlessly. White while parking lights or headlights are on, yellow or “amber” whenever turn signal or flashers/hazards are turned on. Great product, can’t find another that functions like these. No hyper flash either. Awesome.
Great purchase, I have had other brands and have had to install resistors. These are a really nice product.
No hyper flash, easy to install, nice and bright. Very happy with them.
Installed on 2011 ram 1500. Works amazing no hyper flash or anything. Definitely worth paying a little extra to not deal with resistors.
Finally found these switchback LED bulbs with built in resistors for the B5 Audi S4. Bulbs are plug and play, no hyperflash or error codes so far. The bulb are bright and work as described. Thank you.
