Everything is great. I have owned since September of 2022. Being a volunteer firefighter in NH it has always been reliable and work everytime i needed it. The magnets are very strong and have exceeded 80mph even in windy conditions and they do not move. Alittle whisteling, not a big deal turn up radio.

This baby 12 inch light bar is amazingly bright. It has a ton of different flashing modes and is surprisingly very very well built. The magnets are super strong. It's sat outside for nearly two years in New England. Through all kinds of weather. 90 degree days, and 20 degree blizzards. The cord is nice and long and is easy to use with a ton of cool different flashing modes. Even better it remembers the last mode it was on if you unplug it. Only thing I wish I did is got the amber and white version. I saw other trucks with that style and it stands out more. (Check your local regulations). I configured mine to sit ontop a Trac rack roof rack cantilever with some sheet metal, as it wouldn't stick to the aluminum truck body Overall 10/10. It exceeded my expectations

This light bar is amazing! It is super bright and has so many sequences for it. It is burning my retina how bright it is! Lol Great customer service too. Definitely worth the money, and the 3 year manufacturer guarantee. This is definitely the light for first responders!

Bought this light for my ‘13 Ram 3500 plow truck. Overall I’m happy with it. Easy to mount and install. I mounted it to my headache rack and hardwired to a dash mounted toggle switch. It’s nicely low profile and is insanely bright! Has more than enough flash patterns (what the heck is “California Steady” flash pattern?) Only 3 complaints: the wiring pigtail needs to be about 5’ longer for hardwired applications, I had to make my own pigtail to meet it part way; flash mode selection is kind of a pain but you only have to do it once; biggest complaint is that one of the LED panels stops working when it gets colder than 20 degrees out, give it a thump and it’ll come back on. That all being said, I doubt you could find a brighter strobe for the price.

I like the brightness and the flash options, but brightness above all. Does not seem like a cheap light, so far so good

The light is pretty solid considering the price point it's not great during the day but it is visible. At night it's plenty bright . I've used it for my side job as an roadside assistance driver for almost a year now and it's been on the roof almost constantly since then. It did live through one Ohio winter so far. Recently (last couple months) I've noticed one or the light panels is significantly dimmer than the others. It still works but is noticably different. I'd love if this were not the issue or customer service would take care of it but at this price point I'm not expecting a new light out of it. Magnets are super strong although they are rusting and have caused some paint damage to the roof. I'll be spraying them with some tool dip to fix this hopefully. It would be nice if they had a rubber coating or boot from the factory.

This is just about the "real thing." In my opinion, you should go for a Class 1 grade if you plan to use it during the day. Class 1 is the brightest type of emergency light. They are required for emergency vehicles. Originally, I ordered the $45 Xbrite, which gets great reviews. I returned it without opening it. I decided not to cheap out as reviewers reported a lack of effectiveness in bright conditions. I need brightness as I use it for snow plowing, which I try to do during the day. Seems well made. It is much more effective than strobes. UPDATE AFTER A FEW DAYS. I noticed that one of the panels was bad! It would only work intermittently. If you tapped the light, it would work for a while then stop. I returned it and received an immediate refund. This thing came in the product box with no outer box and THE BOX WAS NOT EVEN TAPED! I imagine that is why it had problems. I checked around to see if there was a better light out there. None could give me confidence within the price range. Given the fast refund, I ordered another one. Will update if it works or not!
