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.
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.

Replaced my front park/turning lights with these. Shipped and arrived very quickly. Super simple plug and play install. No hyperflash and super bright. Worth the money. In the picture, passenger side (left side) is the incandescent bulb, driver side (right side) is the new LED switchback this review is for.
Works great as expected
Great lights just a little bigger than expected
Was a little leery of buying these but wanted an upgrade since I had LEDs in the back. Built in resistors are the way to go! Recommend!
They are a solid product from what i can tell they're bright and work as advertised, my only issue i had was some hyperflash due to not enough resistance to the circuit but just barely. They were installed in a c6 Corvette and with the bcm being the relay a 24w 10ohm resistor was installed on left directional only and it was enough to keep from the hyperflash. All in all a good product so far.
I just installed these to replace the one I had with hyper flash. After install I tested them and the hyper flash was gone. Definitely recommend these lights and will be buying them again in the future.
The Switchbacks are fault free after a few settings where changed in My 2018 Ram 1500. They are very bright & have a good customer service.
Very easy install they look very good
Also the Amber turn signals are much brighter than stock
When I first installed these, I got the dreaded hyper flash. Called underground lighting and they attempted to trouble shoot to no avail. The owner Danny stayed in constant communication with me to try and get this resolved. He was even going to send me resistors free of charge. I declined because I didn’t want to splice into the factory wiring...I found a turn signal relay for my Toyota and the lights work great! I highly recommend these lights and Danny is great, however if you own a Toyota and a relay is available, go that route much easier install....
My vehicle doesn't operate these as Drl's, so no switchback functionality is possible, but I do love these amber colored turn signals that get more attn for safety. No hyperflash, no led flicker. Awesome product
