ASPL 2x16.8 inch 32LED Emergency Flashing Warning Strobe Lights Bar With 4 Upgraded Vacuum Suction Cups 23 Flash Patterns Police Cop LED Traffic Advisor Strobe Light For Trucks Vehicles (Red/Blue)

Dead on arrival. Nothing worked or turned on

The light bar came with the necessary hardware to mount it to a windshield and decent instructions. Although they do work, the suction cups aren’t high-quality. There’s flashing on the arms and the plastic feels cheap. One of mine has a warped suction disc. Not sure I would trust them to hold the lights long-term on a vehicle. I’ll be using them on a Truck/Racing simulator, so I don’t need the suction cups.The lights are bright and appear well built. I didn’t see any defects when scrolling through the 23 patterns. Many patterns are similar and without some type of indicator it’s hard to know which one is active. It’s not a problem if you only use one pattern, because the unit does keep the last pattern active even when powered down. But if the pattern gets off, it’s not easy getting back to it.The light bar works, but if I needed one for my real car, I would look for something with better mounting hardware and a pattern indicator.

These are a great and simple set of flashing lights for a vehicle. Thanks to the adjustable suction cup brackets, these fit easily on a slope front windshield or a flat back windshield. It took about five minutes to put the brackets together and very easily sets up in the vehicle.The lights are bright enough and very easily visible from several hundred feet away, providing just enough subtle illumination we need it for work. He easily removed from the vehicle and can be swapped out into another vehicle. They plug right in to the outlet and the button makes it very easy to use. There are a lot of patterns to flip through, however a lot of them are simply the same.
