Bright af. No hyper flash
Great
These LEDs are very bright and no hyper flashing excellent quality
Good value for the money. Work as advertised.
Love them
You might be able to find cheaper LED lights, but you get what you pay for. Cheaper isn’t always better. Underground lighting has quality products and super fast shipping. Highly recommend.
The LED lights that I ordered. Reverse LEDs, stop brake light LEDs, and turn signals. These suckers are so bright. I love them and CUSTOMER SERVICE was awesome to speak to. I highly recommend these LED bulbs.
Super bright, no hyper flash, great service.
Just installed so hopefully will last a while. Look and feel solid, nice design and engineering! They look and work great! Very bright, no issues, very simple to install w/o the hassle of having to install external resistors. They may seem pricey, not cheap for sure, but you get what you pay for. However, when compared to other manufacturers of similar lightbulbs (using external resistors), these are a great buy! Nice work!
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.
