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 SwitchbackLED 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 bulbsare 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.

Does not operate as described.
The description of this item stated it fit my toyota tundra but nothing was in description that this item will not operate as description in toyota tundras. White led only operates with headlights on, which I wanted white led while driving and yellow led only with turn signal.
That is how your vehicle is wired from factory. Some Toyota models are like that and Corvettes.
Your vehicle uses the high filament for drl instead of low filament like most vehicles.

Super easy to install ridiculously bright. No hyper-flashing, complete plug and play. Very happy with the purchase
These switchbacks work great !!
Bought these switchbacks for my 2004 Dodge Ram 3500. And they work flawless. No hyper flash. Doesn't have my "lamp out" light on the dash. And they are super bright and doesn't discolor when you turn the turn signal on with the running lights on. Absolutely great product !

These LED Switchback Bulbs are amazing and well worth the investment.
First off, I've been on the internet for over 6 months looking at the different bulbs (and the hokey add-on resistors) for my SUV. The reviews of them scare the living daylights out of you. From the need to mount the stand alone resistors to a piece of metal in the car (where do you find metal in a car nowadays) they're all plastic and those resistors get hot. Well, I found the perfect answer here thanks to the owner (Daniel), who took the time to explain EVERYTHING, which made my decision easy for me to go with these 3157 switchback bulbs for my 07 Chevy Trailblazer LT. If you've been questioning yourself should I or shouldn't I? Look no further. You've found the right bulbs right here. I could write a book on the bulbs AND the customer service this guy provides. Easy installation. I did it myself. It took me 45 minutes and that was for both headlights. While you're at it, get the LED 9005 & 9006 bulbs for the headlight and the 194 amber bulbs for the turn signals. It makes the vehicle look like its brand new. I'll post a video later. Just goes to show you that customer service is still alive when people value their business. This guy does!!! Thanks Daniel for your help. Respectfully, Rob

Installed these on 2014 Ford F250. These lights are super bright! The white light is bright, but when you hit your turn signals the orange is insanely bright! No body will miss your turn signals and no hyper flash. Had in for about a week and they work great. Would definitely recommend.

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.
