T15/912/921

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.

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.

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 was searching all over for a brake light flash controller that had 3 rapid flashes and then stayed solid for the 3rd brake light on my '18 Silverado. I'm not sure why, but literally every single flash controller I looked at had 3 rapid flashes followed by 3 slow flashes which seems like it would be incredibly annoying. Although I could not find a description of the flash pattern anywhere on this product listing which was quite frustrating, I took a chance and lucked out. As with almost any LED light, it is substantially brighter than the incandescent equivalent. The flash pattern is short but effective. While I would have rather used a flash controller which would work universally even with regular bulbs, I can live with this. Since my 3rd brake uses only one bulb, I will have an replacement ready. A 12-month warranty was also a selling point, but hopefully I won't need to use it.

I purchased these last March, Last month someone told me that my light bulb was starting to go out, I said these bulbs flash, so it looks like they are going out to bring awareness to the drivers behind me. I left it at that. It was sitting at the back of my head that I needed to check the bulb to make sure they were indeed working. Today I checked and it only lights up very dim if any. I made sure that the bulb was in correctly and even made sure that the wiring was working correctly by installing a regular bulb and observing if it lights up. Needless to say, this led bulb did not even last an entire year. They are great when they are working...

I’ve been changing out these kinds of bulbs in our Honda minivans (the high mounted third brake light) for the last 15 years. But these were the first LED bulbs that we had tried, and while we love the brightness and the ease of installation, the first bulb we tried (this was a two pack) only lasted about six weeks. I finally got around to putting in the second bulb yesterday, and so we will see how long the second one lasts. We double checked that these are the right bulbs for the right vehicle, and they fit perfectly and installed easily. The first one just didn’t last, and LED bulbs are supposed to last far longer than conventional incandescent little bulbs or whatever was in there previously. There are no water leaks and the seal into the third brake light is tight, so nothing got wet or exposed to the elements. The first one just simply burned out in six weeks.

I have a 2019 ram 1500 new body style “dt” and I’m Confirming these lights do work for your third brake light bulb replacement. No errors on dash and it is bright. It comes with two led bulbs all you need is one, so you have a spare bulb if you need it. The flashing is a nice function then it stays solid after four flashes less then 2 seconds then constantly on. Can’t tell how long they will last yet but as of now it is working perfectly. Edit. The bulbs lasted 2 years each. So for one pack of 2 you get a little over 4 years. Still not a bad deal.

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.

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!

Fits & works 💯👍. Only complaint shipping cost high. Installed 1 light in Feb 2020...and just over a year later April 2021 the LED strobing 912/921 bulb burned out. The package came in 2s so hoping the 2nd LED bulb last longer, almost $15 per bulb spread over a year.

Used in the 3rd brake light of my Ford Ranger. It does what it's supposed to, but honestly I was expecting it to be brighter being that it is led. The flashes are also slow and lazy mimicking an incandescent bulb instead of a crisp on-off. This may or not be a factor for buyers.
