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 .

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.

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.

I like this 921 Strobe bulb (RED). I installed it in a 2012 Honda Odyssey EXL. It performed as advertised throughout its lifespan. I'm now using bulb 2 of 2 and have already ordered a spare from another brand because I anticipate the one, I'm using to fail well before 30,000hrs expires. The first bulb lasted about 14 months, give or take a month or two. (not aware of how long it was burnt out prior to me noticing it) It's a shame they don't last as long as advertised because I really like the look, brightness and the strobe feature for safety purposes of the bulb. I'm hoping the second bulb will outlast the first, but I'll have a back-up anticipating the worst.

I usually buy Sylvania zevo lights for the brightness this one I would say is brighter than that plus the flashing part of the lights it's extremely bright. Will buy again! Easy to install the color is bright red not faint like most lights. Fits great no problems.

I just installed it and it works just fine. The strobe flashes 3 times then to a solid on in less than 2 seconds. This meets or exceeds the most restrictive laws I'm aware of for brake strobes. The bulb I replaced is a bit shorter than this LED. Specific to Ram truck. FYI: If your truck says rear passenger side taillight is out, yet you have LED taillights, it's likely your third brake light. This should fit many model years. Mine is a 2016 Ram 1500. To install, remove the two Phillips. Pry off third brake housing with fingers. You'll see 3, clear, 921 size bulbs. Outside 2 are for cargo bed and middle is brake light. Twist the bulb housing to remove (look inside to see which way it can twist). Pull out bulb and replace with new one. Twist bulb socket back in place. Wipe around gasket on housing and sheetmetal to ensure a good, clean seal. If you struggle getting housing back in, ensure you're lining up little tab just under screw. Once it's back in place, replace screws ensuring you don't overtighten and the screws have the gasket washers still on them. That's it! I chose the red strobe only because the white strobe gave me a warning saying I may need an extra part due to the power draw. Not sure if it really mattered.

Does it "Fit" a 2019 Traverse? Yes it does, but does it work properly? No. Because most Chevrolet vehicles these days are designed to have their reverse lights illuminate when you unlock the doors, there is always a small current flowing through what appears to be a small mother board or electronic board of some sort in the assembly itself. Because this, and many other led bulbs I have tried are very efficient, that little bit of continuous curent results in the bulb remaining dimly lit even when the doors are closed, locked, and the engine and all interior lights are off. When illuminated, the lights are very bright and appear good quality. The other thing is the strobe is not as rapid as I would have liked. Disappointed that it didn't work, however in almost any other vehicle I'm sure they would be perfect.

Nice bulbs, good quality, fit in my 2002 E350 3rd brake light bulbs just fine. The flashing is a nice feature, especially in Arizona where most drivers don't know how to pay attention. Bright red in the red housings, very clear and easy to see.

Very nice lights, they fit great and were easy to install. Installed in my 2000 Nissan Pathfinder and 2010 Chevrolet Cobalt. Super bright lights and I love the strobe flashing as it turns on. Great way to get people's attention.

Fits great easy to install and works awesome. The strobe, 3 flashes before steady, works well to catch attention.

Highly recommend alla lighting, great company, well packaged product and does what it says it will do. The bulb was a bit too tall for the housing for my car, but i managed to install it no problem! Would recommend to anyone looking at alla lighting branded products!

Very nice product, fit easily , one minute installation, the brightness is incredible and the three times flash before running on is amazing, llllllooooove it

Received 2 LED reverse lights, easy install and they work superbly (and are very bright) on our 2023 Toyota Corolla XSE Hybrid AWD.
