LINKITOMLED Strobe Flashing Light Bar -Double Side 30 LED High Intensity Emergency Hazard Warning Lighting Bar/Beacon/with Magnetic and 16 ft Straight Cord for Car Trailer Roof Safety (Amber&White)

Great looking and works really well day or night on my vehicle. Easy to take magnets off to bolt on.

purchased this for bad weather to make my self more visible to the blind drivers out there. its very bright and has some decent flash patterns. the magnets are good and should hold at highway speed. There are holes that the power wires run through that dont have a gromet or any sealing so i wouldn't hold by breath for this to last long if exposed to a lot of rain. i took some black rvt and filled the holes to secure the wire from chaffing and to seal it from water. i honestly dont know how often ill use it but if i do the weather needs to be extremely bad. i will update if i do use it and how it performs.UPDATE: Today i used it to test it out. this morning was 24 degrees out and the magnets held perfectly even though the roof had a layer of frost on it. they held at 75mph and had really good light throw. i ran it 4 hours straight and it didn't skip a beat. im impressed.

What I liked about the light is it’s very bright and has a great selection of flashing options .Magnets were awesome: What I dislike I Bought this light to use daily on my rural mail Route have used it less than 3 months and have it plugged into a 3 hole adapter mounted on the dash which is plugged into the cigarette lighter which is unplugged when not in use . The lights plug is never pulled out of the adapter. Friday while using on the route I noticed the light had quit working after making sure that the adapter was plugged into the cigarette lighter and that the light was plugged into the adapter and turned on I unplugged the light to find that the end had come unscrewed and the parts had fell into the adapter shorting it out and I can’t get the parts out of the adapter so I’m out the price of the light and the 3 hole adapter after only 3 months of use . The last light I had lasted 3 yrs without any problems! Now wishing I had keep it instead of selling it with the car it was mounted on .

My only problem with this lightbar is the controller is built into the cigarette lighter plug, so there's no way to wire it in to separate switch without adding a switch controlled outlet or modifying it with some cutting and splicing.

Perfect for my Tacoma. Now I feel more noticeable and safe when driving my personal vehicle on the job site around other heavy equipment. Magnets are very strong and was super easy to install right out of the box. I love how the wire is long enough to be tucked away and out of site. Very well made product.
