XRIDONSEN 2 in 1 Red Blue Traffic Advisor Police Light Bar 144 LED Interior Front Windshield Dash Rear Window Police Lights Emergency Strobe Warning Hazard Safety for Vehicles Trucks (2x17.7 inch)

It would have been 5 stars, only reason it lost a star was the directions to place the mounting bracket, was very indirect, stating to just put in the screws. There were two different types of screws, I’m not sure what the purpose of the other ones were (the ones that were pointed without washers). But I just had to guess where the screws went based on what fit better. The correct screws for the bracket that holds the suction cups is the one with the washer. But otherwise, it’s a bright light, love how strong the suction cups are and you’re definitely getting a bang for your buck!!

Wish they were a little brighter but they will do the job. First one I ordered came broken but they were quick to swap it out.

I bought these lights to use on my POV for traffic control. Installed on a 2018 Chevy Silverado. They do require assembly of adding the brackets to the lights, all parts provided. Simply just adding bracket and two screws in each side. Many different strobe patterns. This video is early morning use (7 AM). I bought different lights from a couple different vendors. These held up the best. Others had issues where suction cups weren't hold up. These have been on for a week with no issues. I ordered another set as well to add on the side windows but am waiting for extension cable, they the cord between the lights wasn't long enough.

Lights work magnificently. i work security in Portland OR and these lights have done numbers to scare off the tweakers from the buildings i work in. I recently lost one of the brackets and some of the hardware and the company was extremely generous and shipped me new hardware free of charge. Will definitely order again from this company.

The lights are bright but not amazingly bright. They have many patterns to choose from. I out them in the rear window and they do work well. Suction cups are not the best but just make sure window is clean and they should work fine. I've had these for several months and no issues as of yet.
