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

Simply place the light in and plug it in. But don’t go faster than 45mph! I was doing city driving in Phoenix using these for Amazon package delivery and it scratched the roof of my car when driving.

So far these lights have handled over 75 MPH on interstate driving for over 400 miles. They are pretty bright at night time and dusk not sure so much during daylight. So far so good. However could change when it rains and snows out.

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.

As advertised, no problems, works fine.

We deliver for Amazon flex, lyft, and other delivery services, this is a fantastic light for safety while having to stop and start for deliveries, its visible at night and daylight, its multi flash functions give me the options I need for visibility, the extra long cord allows me to plug in up front and control the modes right from the driver seat and have the cords safely stowed away, for safety wr have one for each of our 3 cars.

Tried these after we had three other lights fail after a short time. Still going strong, even in a harsh, northern climate

Brighter than expected and like the multi flash sequences you can choose from. 10 ft cords allow direct wiring if you want but you will lose ability to choose flash sequences.

Very bright, even in daylight. I was amazed.

Really strong magnet.

I really like these lights. They are really bright and have several nice flash rates and patterns. I think they are a good value.
