Outstanding visibility, especially at night.
I could tell immediately the lights were high quality. They were simple to install on my 2023 Ford F150 XLT. The LEDs may a huge difference in the amount of light be generated and not having to install resistors are absolutely worth the extra cost. Plug and Play. Great product!!
2021-23 Ford F150 Red Rear Brake/ Turn Signal LED Bulb W/ Built in Resistor No hyperflash (PAIR)
So far 10/10 I’ve had zero issues with them love how they look love how bright they are I recommend them to my friends since I’ve put them in
So far I am happy with the way the lights look and work. I hope they last a long time.
They are extremely bright, I definitely recommend them
Super bright my old ones sucked really bad and these lights changed the way my truck looks
I had to modify the sensors because they were not thick enough or wide enough to fit in my sockets, but after I modify them, they were fine. They just would not hold into the sockets. So I ordered the new 4337. I believe models should fit my sockets.
Just received and installed the amber led non hyperflash bulbs, they look & work great. Danny is great to deal with. Thank you
They work as intended just plug and play great quality for reasonable price!
Love the change
Had to do some of my own wiring since the car was older, pretty much plug & play just had to add a wire pin and T-tap into another wire!
Due to several LED lighting issues with other products experienced on my 2006 Toyota Sequoia (LED Headlights), I contacted Danny @ Underground Lighting inquiring on products/services based on the many reviews. He assured me I would not experience a problem on purchase and provided extraordinary customers service guiding me through the replacement products needed for my vehicle internal/external lighting upgrading all with LED products. Although costly, I am truly satisfied with the decision and 3 years in haven't experience the same problem (LED Headlights caused issues with vehicle ignition). Recently, however I had an issue with the purchased LED dome light and contacted Underground lighting for assistance. He assisted me with troubleshooting which didn't address my issue and just decided to replace and upgrade me to the newer LED bulb.
I am again a satisfied customer and would recommend Underground lighting for your LED product needs.
Thank you UL for providing quality customer services and superior Products.

Best purchase I’ve made would recommend anybody need lights to see these guys.
Very big improvement and great replacement for the engine compartment lighting
Blink blink blink
Recently installed a pair of these bulbs on my 2015 Jeep Wrangler. Very impressed with quality, brightness, and no hyper-flash!
Bright, easy to install and great information on products.
Totally refreshed the trucks appearance. Bought the running lights a couple of years ago and was really impressed. I figured for the money I’d wait and see if the product was proven. Well Underground lighting delivered! Two years later (today) I’ve purchased headlights and fogs(LED). Last night I went out for a cruise to see what I had going on, well not to my surprise it was like driving during daylight! Very pleased! Thanks for taking pride in your work Underground Lighting!

Installed the 3157 LED bulbs in my 2015 Jeep Wrangler one week ago. No problems yet! Seems to have quieter fans than the last set of tail lights from Underground, but time will tell!
These leds work great! Bright
