Not worth it. Sometimes it does not work. Then you have to give a tap to work. Do not recommend. Do not invest money on this bad product.

This is a review of "4PCS Universal Wireless Car Door LED Warning Lights, Car Door Warnning Lights, Roadside Flashing Flares Safety Warning Light, Strobe Lights for Anti rear-end Collision - Blue"These little flashing light pucks add a new layer of safety when opening your car doors. As the door opens, the light is pulled away from the mounted magnet that turns the light off. It the progresses trough a pre-programmed pattern of flashing, then eventually turn off if you leave your door open for while. They increase visibility of your door when opening, so drivers coming from behind will be sure to see you from a distance. The mounting process was easy and quick; they fit nicely on all 4 doors of my BMW i4.

Cute, but cheap. It's overpriced & worthless. It's inconsistent, i.e., sometimes it works & sometimes not -- it may or may not flash when door is opened; & will flash after it is closed. Tiny & weak magnet (very thin) makes them useless. They aren't even worth it for half the price. Save your money. A best, it's an expensive Christmas decoration.

This product is only compatible with older motor vehicles. It is completely useless when it comes to modern cars. I attempted to install it in my 2013 Toyota Sienna XLE, but unfortunately, it ended up damaging the paint on the driver-side door.

Don’t do it.

I got these thinking they might be useful when opening the car door in a parking lot at night. They flash or twinkle and dont emit a steady, blue light instead of a clear light. The light isn't bright enough to light up the ground or the doorway of the car, and might attract unwanted attention at night instead of lighting up the area around your door. The lights are a little larger in diameter than a quarter. They're flimsy and probably will crack easily. They come with double-sided stick-on dots. I had a lot of trouble getting the backing off even using a razor blade. They come with a disc battery and a flat magnet about the size of a dime. The magnet turns off the light when within about a half-inch of the light. When I was carrying the lights to the garage to put them on I dropped one of the magnets from less than 3 feet above the floor. The magnet broke in half. The instructions were printed on paper about half the size of a business card. I had to use a magnifying glass to read the print and even then it was hard. The instructions barely make sense. At one point when describing the stick-on dots it said "it's better to bake on with a sticky stick." I can guess what a sticky stick is but I don't know. Fortunately the package had 4 lights in it with 4, CR2032 batteries, which are common for my use. So if I throw away the lights, I will definitely keep the batteries. I wouldn't order this product again, and will probably remove the lights. I gave it 2 stars because of the batteries.
