Worst exactly how it should. Even though I shouldn't have done it, it stayed on top of my roof at a 110 miles an hour. So the magnet and the suction cups that mount it to your roof work really well if I was you, I would take my time and run the wires, right? So they don't get tangled, get shorts and and quit working.

8 months in still working great

Very bright

Talk about magnet strength! Husband loved it and said it installed easily and held up through rain well. Very bright and visible.

Honest review time!! The light itself is great. It's bright, the controller is easy to understand. They give you 2 different power pigtails depending on how you want to power it, but my hardwire pigtail doesn't work. Only the cigarette lighter plug. I'll end up fixing that later on. NOW...pay attention here, they claim that that magnets/suction cup combo will hold at highway speeds. But given that the magnet strength is only 30lbs each, yeah....that's a hard NO. Do yourself the favor and spend the coin and get you the 120lb rubber coated magnets. That's 4x the original working strength. Mine needs A LOT of help to move since I did this upgrade. Thank me later

Easy to install, would highly recommend

Update: seller promptly reached out and offered to ship a replacement. I've received the replacement and it works as expected. As a mail carrier, the company provided beacon is a joke and this light bar knocks it out of the park when it comes to staying visible on the shoulder of the road. Very easy to use as an extra turn signal with the remote control. All around happy with my purchase. 10/10 customer serviceI am a mail carrier and used this for 10 months and now it doesn't work in the front. It stays on dimly lit whenever it's plugged in and the switch on the plug-in is turned on and lit up red. It's not supposed to be on without the power button being pressed on the controller. Very frustrated I wasted my money. Was expecting it to last at least 2 years.

You get what you pay for. Very cheaply made, but also cheap to purchase. The light itself works fine thus far, but the magnets with the rubber suction cups are garbage. I had to move the light to a different location on my truck and it removed very easily while leaving the suction cups behind. I also have ribs on the cab of my truck, and there is no way to adjust the brackets on the light, so you either need to place it off to one side, (which looks very dumb) or place it on the ribs and cross your fingers that it holds. If you have a flat surface, I'm sure it'll be fine. Good luck.
