Alla Lighting 2600lm T10/T15 912 921 Strobe LED Back-up Reverse, 3rd Brake Lights Bulbs, 6000K White Super Bright 922 W16W 906 4014-SMD Flashing Lamps for Cars, Trucks, RVs, SUVs

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.

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.

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 initially bought these for the high-mount brake like in my 2004 excursion. I specifically wanted the strobe effect to help terrible drivers from rear ending me. They are bright, intense, and lasted well. I had to replace them just today. That’s over two years and six months. And I only replaced two out of three. One is still going strong. As I did once already, I will buy again.

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.

The media could not be loaded. Flickering is in point, definitely a upgrade for safety on my car hopefully they last a while.

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.

The media could not be loaded. 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.
