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.

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.
2014 WK2; Jep Grand Cherokee Laredo with the halogens...
These lights are glorious! There is no guess work whatsoever. Pop them in and you get a bright white light (that does a reasonable job at adding forward illumination themselves) and once the signal is turned on, there is the crisp amber.
I will note that apparently, the signal is one of few bulbs the base model's computer monitors. In my Jeep at least, it thinks the signal bulbs are out, but have confirmed that they in fact working properly and blinking at proper pace, despite the computer indicating otherwise (fast ding and blink on the instrument cluster)
Lights are exactly as described. Perfect 6000k white light and super bright switchback amber for the turn signal. No error codes on my Jeep Grand Cherokee either which is great considering how sensitive these cars are. I’m very pleased with these and will definitely order from underground again!!
I bought these for use in a 2015 Jeep Grand Cherokee. They installed easily (no need to be concerned about polarity - they fit and work either way). There is no hyperflash and no dashboard warning that a turn signal is out. The white part comes on when either the parking lights are on or the headlights are on. During normal running in daylight they are amber and amber turns. They work perfectly - and the service from Danny is unmatched by anyone I've ever dealt with - he's definitely customer oriented and his product is excellent!
Underground Lighting is first on my list of go to places for lighting now. Thanks Danny!
First plug and play LED lights ive installed in my truck (07 ram 2500) that work right out of the box!
Excellent build quality. Very bright. No hyper flashing but the switch back feature is not compatible with my 2021 Miata. Otherwise an excellent product.
They are real bright and work like they should.
These switch back lites work great. No additional resistors required. Used resistors on previous bulbs and they got so hot they melted some plastic!
