I was having trouble finding the right turn signals for my vehicle, but a quick call and couple pictures sent and 5 min later I had the right ones ordered. They are very knowledgeable and honest and the products are outstanding

These were a perfect replacement for the halogen bulbs on my 2021 F150 brake lights. They're bright and crisp. Install was quick and easy. Note they're slightly wider than the halogen bulb and will need a little coaxing to get in, otherwise no issues. Very happy with this purchase.

I bought these lights a couple years ago for my 07 NBS Silverado and at the time I only changed out one side of the truck (so I got the amber ones too) and the ambers have lasted this long with no issues but the set of reds I bought both died within a couple months of each other just recently. So I changed out the other side of the truck as well as buying another replacement set for the reds that recently failed. Noticed too that these new sets of reds are designed a little different visually compared to the old set, so hopefully something changes for the better.

Otherwise I really like the lights... Nice and bright, seemingly good construction, no hyperflash, so I hope these last a bit longer this time. And maybe it's wishful thinking for longer then 2 years but I might look somewhere else next time if they die in 2 years again.

Shipping was very fast. The lights seem of high quality and they are nice and bright. Would diffently buy again.

Excellent ! Hope they will last more than the first set …

Just arrived and it is 15 degrees outside… waiting until I have warm weather, will let you know. TY

Needed a brighter bulb due to a blacked out housing being less reflective, wasn't disappointed. Also, I haven't experienced any hyperflash. Very satisfied.

I bought the kit for my ‘15 jeep grand Cherokee with halogen capsules cause hologens and projectors don’t mix. I’m pleased with the light output and the overall ease of install. I would recommend removing the whole headlight assembly to install the kit as it is a pain to get to the housing for the bulb. The customer service was excellent as I had an issue figuring out the the wiring diagram (my issues not UG lighting) and he helped me sort it out. Over would buy again.

I have these on both of my trucks now and I love them. Well worth the money

I was a bit hesitant because of the price, but these turn signals are definitely worth it! They look fantastic and work perfectly on my 2000 Honda Civic EK Hatch, no hyperflashing issues at all. The switchback feature is super cool aswell.

In the video, you can clearly see the difference, with the right turn signal showing the old one for comparison. The brightness and style of these signals are a huge upgrade.

On top of that, the customer service was excellent, quick responses and very helpful throughout the process. If you’re on the fence, I highly recommend giving these a try!

great product

With many companies saying their leds are compatible with no Hyper Flash or errors, Underground actually delivers a product that works perfectly the minute you plug it in. Outstanding quality and error free operation.

2021-24 Ford F150 Red Rear Brake/ Turn Signal LED Bulb W/ Built in Resistor No hyperflash (PAIR)

Love the brightness but are not at all happy having to replace expensive bulbs in 2 years

Just as advertised. Thank you very much! Didn't need the relay switch, but I'll keep it anyway. Lightning is just as bright as I like it. 👍🏾👍🏾

3157 Switchback LED Front Turn Signal Bulbs White Amber | Built in Resistors Dual Color No hyperflash

I’ve been looking to replace my halogens to LEDs for a long time. First, LEDs are way brighter than halogens. Second, LEDs turn on faster than halogens. This should give the drivers behind me fair warning of my intentions. These LEDs are awesome! Much brighter and crisper. The only issue I had was that the base of the LED made the socket expand ever so slightly. The LED is super snug and not going anywhere, but it took a bit of finagling to get it back into the housing unit. Works as advertised; no hyper-flash nor any errors.

The tag light bulb is very bright but the bulb is too large to fit securely into the factory housing

Great light real bright work great

fast delivery

Installed on my XLT, & they do excellent as described, I’ll be buying again for my fleet F150’s

Literally night and day difference

Perfect fit and no canbus errors or hyper flash as advertised. Fast Delivery!!! I will continue buying from Underground Lighting in the near future.

I ordered these after going through frustration of ordering bulbs on Amazon. I got tired of hyperflash. These work flawlessly, and I am very happy I found this site.
The shipping was fast, and worth the wait. Very bright lights, and work as advertised.

Amazingly Bright
