Review: Beautiful on my Mercedes Benz GLK 350 - A real nice look on my GLK Mercedes . As you put car in reverse it strobe 3 times with bright light making it easier for someone to know that you are backing up . Very easy install . Just plug & play . No error code .Works flawlessly. With this car the harder job is that you have to take out the whole light fixture . It’s held on by three Bolts . Once you remove it you unplug the Harness . Let me point out . With this Car once you remove the Rear Light Fixture all the other Lights are sealed as they are already LEDs . The only one that is not an LED is the reverse one which is at the bottom and the only one exposed . Good company ALLA that makes the best strobing LEDs .
Review: Bright, easy and cheap - I just bought my second set. I highly recommend them as they are easy fit for oem bulbs and are significantly brighter. One of the pair began to flicker and die after about 4 & 1/2 years, but that seems like a more than reasonable amount of time for the cost of these lamps. As you can see in the photo, the LED diodes aren’t exactly precision installed, but you are still getting more than you paid for. If installation is particularly difficult or time consuming, then a more expensive lamp is probably a safer choice in terms of longevity. But on my car, it look less than a minute to swap back up / reverse lamps, so the price is right for these as they’ve held up longer than than I expected.

### ⭐⭐⭐⭐⭐ Super bright and super cool!
*by J***D on July 18, 2020*

These are super bright compared to oem! They fit nicely in the SuperLUX V2 tails on my Genesis Coupe as well. The flash on/off feature is pretty sweet; as it looks more custom, and it also adds safety. If someone doesn't notice me backing up with these things; then they need glasses 😂. This is my first day with them installed, so I cannot comment on the longevity or if they'll cause any issues. If anything comes up, I'll be sure to edit my comment. Fingers crossed though, but they do have a year warranty, so we will see what happens. I posted a video and some pics. One of the pics has a comparison of these LEDs vs the OEM.
