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 splicing or complicated wiring for 99% of vehicles. This light is a plug-n-play installation and operation.

they work good wish they were on during the day. Were little hard to get in it almost feel into the light because the LED isn't much smaller then the hole and when you pull it out it catches and pulls out of socket and fall into light. like to try some LED's for my tail lights
The original set of 3157 switchbacks I purchased for my 2016 F250 had an issue with erratic flashing and flashing white every so often. Worked with Danny and he ended up sending me a different set that work as expected. Really love the all white light look on the 2016 F250 given that the turn signals are huge on this truck.
Very bright and no hyper flash. Plug and play at its best!
Bought some led switchback turn signals for my 06 f250. They were very bright with no hyperflash. A true plug and play.
The switchback turn signals are impressive. They are bright, almost like having an extra running light.
And, no hyperflash either on my 2015 Ford F150 XLT.
Only thing I noticed...occasionally the turn signal will flash white instead of amber for just an instant. Only noticeable on a dark night though.
Bought for Christmas. Can’t say how they work until then. Received parts very quickly. Thanks
Added to a CX-5 Touring, works great. Install was a breeze.
2017 Honda Accord Sport…
Tried 2 other brands that said their LED’s were ‘plug and play, no resistors necessary’. Both came with resistor kits, just in case, of course. Both sets hyper-flashed even after taping in the resistors. Found Underground in a search and having the resistors already in the set and having the fan for the turn signal operation made perfect sense. 8 minute switch out and they were up and running flawlessly! Nice and bright running lights and perfect switchback with NO HYPER- FLASH! Should’ve done my homework first to avoid the frustration.
Plug and play install, super bright. Color change works flawlessly. Would buy again.
They work perfect so far... exactly the right fit and look amazing. Thank you.
