ASPL 2x16.8 inch Emergency Flashing LED Traffic Advisor Strobe Light Bar 32LED 26 Flash Patterns Interior Safety Warning Lights (Red/White)

Suction cups on anything is useless where I live as it is too cold around here. However, they do give you some doubleside sticky discs for inside the cups to "permanently" install to the window. There are other mounting brackets as well for various choices in installing. The lights work great. I only wish there was more of an indicator as to what pattern is being used. I'd prefer 4 or 5 patterns to make it easier to jump through to the needed "arrow" or flash.. But for some reason everyone wants a ton of patterns (I"m guessing mostly those who have these for show and not practical uses).

Heavy duty and bright. Had to use the sticky pads that came with it because the suction cups wouldn’t stick well on my back window because of the rear defrost lines.

I work for the SHA and run a John Deere tractor cutting grass on the shoulder and median and it only had hazzard lights so I bought this and it's a lifesaver. I recommend this.

Finally got around to installing the light bars. Glad that I got them with the extended return window, because with this kind of wiring, out of the pack, I may request a replacement.They work, lot of patten selection. So that's nice. Probably be a 5 star without the frayed wiring.

Good-very bright. Even during the day time these lights are plenty visible to drivers- easy to install. Everything comes in it’s own baggies, and all parts.- no reflection on windshield. The lights don’t blind you, the driver. So you can still see while you’re driving.Bad- suction cups aren’t strong with just water. If you live in a cold climate I’d recommend using rubbing alcohol and Vaseline. The rubbing alcohol has a much lower freezing point. The Vaseline will help seal the alcohol inside.- no instructions on how to assemble. I had to go back on Amazon and look at the picture too see how the brackets get put on.Things I wish I would have known- pretty sure these are meant to be for back windows because I had to cut the top suction up hole off on both lights because they were blocking my view while driving with them on. They sit too low from the top of the windshield.-theres a lot of spare cord between the lights so I hope you have a good place to hide it.Overall very good product and it does exactly what it’s supposed to do. Very satisfied with them and they’re priced very fairly. Highly recommend.
