2X 10.7 inch Emergency Strobe Lights Bar 24 LED Amber White Warning Flashing Safety Dash Side Window Front/Rear Windshield Lights Grill Surface Mount for Construction Vehicles Tow/Plow Trucks

Well, it looks like I'm the first reviewer.Assembly was simple. You only need a Phillips head screwdriver. (And a small nut driver if you are installing in the grill.) I am in 100F+ Texas heat, so I went ahead and used the adhesive discs that come with it. The cups are sufficiently deep that you can stick them inside the cups and then peal and press to install on the glass when you're ready. Most suction devices have some trouble here, so I went straight to the discs. But these are large cups, so it may not be necessary for everyone. But the discs are also clear, so there's no visual difference.There is plenty of cable, both power and between the units. There's enough between the units that if you need to run an odd route between them, you could.The unit looks and feels solid for this price point. Note that you must install all end bolts to make them waterproof, even if you don't use the brackets. I have high hopes, because the cups are large and there are four of them per unit. And they're not too heavy, so I don't see them falling off in my dry installation.I mounted them inside the rear glass of a 2023 Explorer. There's plenty of angle adjustment available. The Explorer has quite dark factory rear tint, and the lights show well. Even in daylight, these red/white's are bright enough to get attention and give notice. A very discrete installation that few people passing will see if it's not running. Usual control scheme. A power switch with pilot and a second button to cycle through the many flash patterns.I'm a retired paramedic and peace officer, and I want to be able to stop and give aid when needed on the road, and these are to give me some protection. They seem fine for that without spoiling the vehicle profile (or drawing the ire of my wife). I'd want a bit more all around if I wanted to work traffic construction extra jobs. But if I had to stop in the roadway to cover a victim, I think these and a half dozen LED strobe flares would work.

Easy install, bright, different patterns, great safety lights.

Lights are bright easy to mount and has plenty of cord for my installation and has lots of different settings for light modes

Super bright leds especially for the price point. Easy install and the adhesive helps the suction cups tremendously. Assembly was ok. You do have to apply a fair amount of pressure to the screws to get them to catch.

Great strobe lights can be seen from a long distance even during the day.

Added these to increase visability from behind when I am on track to ensure racers can see there is issue ahead.....Super bright, extremely effecient, easily placed, Suction cups hold tight and easily stored when not needed.....

Update - the seller reached out and helped make everything right. The reason I'm upgrading it to 5 stars is because the seller genuinely seemed to care and help and resolved everything and never asked for a 5 star rating in return (I've had some companies say I'll refund your order if you give 5 stars etc but not this seller). Because of this I've decided to raise it to 5 stars.I wanted to start off by saying that for the price these are decent quality lights. The flash patterns are effective (although a bit dimmer than I expected) the lights are quiet and the cord with the disconnects was a great idea. I do have two issues however. One, the cigarette lighter is slightly oversized meaning putting it in or taking it out seems to be a hassle and scrapes the cigarette lighter. Two, the suction cups do not work. They will last for a few hours and then fall off. If the suction cups were a better quality I would give this five stars or if you plan on mounting this using a bracket and no suction cups this is probably a good choice for you for the price.

Worked right out of the box. As bright as I hoped they would be.
