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 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 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.

Lights worked good nice and bright and super easy to install. Would like to get all lights for my truck eventually
no issues working as advertised much brighter than original . It’s only been installed a little over a week. No hyper flashing so far
Great bulbs from this company I just threw them on my 04 Vette. They’re extremely bright and the switchback work perfect, I did install new blinker housings making them even brighter.
Now will they stand up to the test of time.
True plug and play. Put new LED bulbs in, turned on directionals, parking and DRL. No hyper-flash, no error codes, outstanding. Highly recommend Underground Lighting and their products.
I love the product I wish I had enough money to put them on my old truck someday!! Great product I recommend it to anybody.
perform as advertised. happy with the product. using them on my 2000 C5. a worth while improvement over the o.e.m. setup.
I installed these 2 days ago on a C6 Corvette and was initially concerned about turn signal hyper flashing. I’m happy and impressed that they are working as advertised without any hyper flashing! So no need to add separate resistors.
These switchbacks with the built in resistor install easily and work great. Hoping they last...
These bulbs are awesome! Plug and play and are very bright! Used them on a 2002 GMC 1500 and a 2004 Chevy 1500. Will continue to be a return customs and definitely will be telling my friends and family about these!
Super fast delivery! Super bright and perfect fit! I just made my 2nd order!
