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 insure 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 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 blinks 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 "switchback" to white again.

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
I accidentally purchased the wrong switchback led bulb. I noticed my mistake a few minutes later. I purchased at 5am, send a email by 5:15am. I seen they didn’t open until 9am by 9:02 I had a email response!!!! Absolutely great customer service, they changed the bulb to correct size no problem. Then I received a email about shipping and for a few more dollars had it upgraded to 2 day shopping and I received it by 11am the next day! Absolutely impressed with this company all the way around. The product is a true plug and play. It took maybe 5 min to install. Buy these!!!!!
They work fantastic. When I use the turn signals I get a “parking light out” error, but as soon as I turn them off the message goes away, and they work like normal. Worth the money in my opinion, and very pleased with what I got!
Fast shipping and good quality and good fit.
they fit real good and really liked how bright the amber lights work for my turn signal and how bright white the drl's are for my daytime running lighjts
Danny is the man!!! I got the front and back lights. It's been almost two months no more hyper flash problems. Bright lights.
