4pcs LED Flash Strobe Controller, 80W Universal DC9‑26V 16 Strobe Modes Brake Light Flasher Brake Light Strobe Module, Car Flasher Module for Motorcycles Cars Trucks for Brake Light Tail Stop Light

Installed on our military 5ton brush fire truck. Easy to install and works great. Nicely priced.

These LED strobe lights work really well and are very bright. They were easy to install, and the different flashing modes make them perfect for adding visibility to my vehicle. The controller works smoothly, and all four lights function exactly as expected. The quality feels solid for the price. I’m very satisfied with this set and would definitely recommend it.

works as advertised however they do not tell you that the time of the flashing lights in the flash 4 times then stay on mode, the flashes take about .5 seconds total wish they were about 1 second on then off1 seconds 4 times then steady on. wanting to use them on UTV brake lights to better get the attention of drivers behind me so that they don't hit me from behind. So they do work just not how I was thinking they would

Great product worked as advertised

I’m preeeeeeeetty stoked on these. Very straight forward install if you’re familiar with wiring - one side in, one side out. It took me a minute located the numbered switches to change the strobe patterns, but it turns out you have to pop the cap off the board itself. I have one also wired to my chase light and it works just as well. I’d recommend these if you don’t have a designated strobing panel.

Ordered these twice, first time they didn't show up, this time they didn't work. Plugged in all 4 and none of them did anything.

Works great and waterproofed nicely. Used on my fishing kayak to make the white light on my flag pole flash for better visibility.

Instructions do not tell you how to change modes, and I couldn't for the life of me figure out how. The default mode has a long delay after flashes before the light comes on solid, which is not suitable at all for a brake light flasher.

Unlike other flashing modules that only do a few fast flashes, then a few slow ones, and then solid, there are 16 different modes you can choose, including specific ones for LED bulbs vs. halogen. Plus, this one is much smaller, so I can fit it in the lamp housing of my scooter.

No problems with them so far - will update as I use them more outdoors. They can be a bit difficult to pop open but that's to be expected. The LED flicker mode seems to flicker at around 20hz if I had to guess so, quite fast.

The product indicates black/red side as input. I tried two from the package for an led brake light set up. Neither would create a strobe. All I got was a normal steady light. I've used similar ones in the past, so it's not that I don't know what I'm doing.
