ASPL 2pcs LED Warning Flash Beacon Lights, 60 LED Amber Warning Safety Flashing Strobe Lights with Magnetic and 16 ft Straight Cord for Vehicle Truck Tractor Golf Carts UTV Car Bus,12V-24V

Kit comes with two yellow/amber lights. These lights have pretty strong magnets on the bottom to hold in place so that on a vehicle they would work up to at least 50mph. The long 16ft cord allows it to be placed relatively far from the 12v (cigarette) plug power source. There multiple light options from steady to different flash speeds. The light is bright and easily visible from long distances. These are excellent for being seen on the road at night and Ive put one in each of my vehicles for emergency purposes. They would also be useful for temporary use for a delivery vehicle or any other situation where some type of warning light is needed. Very good, highly recommended.

Bright LEDs make it easy to see vehicle while delivering mail. Easy to place on top of vehicle and like all the different strobe patterns.

Sold two lemons, neither of the lights worked.

Muy bien

Appears to be very good quality and will see how they stand up to the weather

Wire to them is extremely light but they work

Not very bright and not waterproof

It exceed my Expectation the brightness of the Strobe Light

Bright and good

These do exactly what they claim, they use magnets to stick to your car, plug into your cigarette lighter and flash brightly. Brightness is goos and it is easy to flip a switch and cycle through patterns of flashing to find one you want, though I suspect that having more than one or perhaps two patterns of flash really won’t matter to most people. I tried sticking the magnet to a curvy surface on my car and it still held well enough to stay on a parked car. My Jeep SUV has a 12V plug in front and in the rear, so I could use both of these at once, but I suspect most users will only be able to use one at a time. These will probably do what you want them to do unless you have unrealistic expectations.
