Botepon 4PCS Universal Wireless Car Door LED Warning Lights, Safety Lights, Strobe Lights for Anti rear-end Collision (Red)

I used this device for a Mandalorian cosplay in my mines worked great

This is a terrific set of safety lights. Installation was as easy as could be and only took a few minutes. You might look at these and think they couldn't be very bright but, surprise, these really put out the light. The flashing patterns add additional safety with the frequent changes. I was really kind of blown away with the ease of installation and the efficiency of the lights and the distance from which they can be seen, especially at night. The magnet that goes on the door frame to turn them off is very powerful so exact location is not necessary and you can test your setup because the magnets can be moved until you use the adhesive pads. The 3M adhesive is very strong and lasts a long time. Clean the area around the pad before you attach the light or magnet because you have a few minutes to relocate either before the adhesive really sticks. As soon as I installed a set on my car I ordered another set for my other car. More than 6 months later they are still working well. I highly recommend these flashing lights for your safety.

I don’t like that theses lights are hard to place and line up to contact each other. Also, they are too thick to fit the door jam in both my Toyota and Ram truck. So, the light were a small waste of money!I wouldn’t recommend them to any car owner.

If you're concerned about your safety when opening your car doors on busy roads, these door magnets could be a great solution. They use flashing lights to signal oncoming traffic, alerting drivers to the fact that you're about to open your door and helping to prevent accidents.One of the biggest benefits of these door magnets is that they can help improve your safety on the road. By signaling to oncoming traffic that you're about to open your door, you can reduce the risk of accidents and potentially save lives. The magnets are also easy to install and use, making them a great choice for anyone who wants to take steps to protect themselves and others on the road.However, it's worth noting that the adhesion of these magnets may not last for more than three years. You may need to replace the magnets or reapply them to your car door periodically to ensure that they continue to work effectively. Additionally, I had to replace a battery and the light would not screw in, which made installation a bit more difficult. I had to press it against the wall, which in turn cracked the red water-tight cover. This required me to use super glue to re-waterproof the device.Overall, if you're looking for a way to improve your safety on the road, these door magnets can be a great choice. They're easy to install and use, and they can help prevent accidents and protect you and others on the road. Just be aware that you may need to replace them periodically, and installation can be a bit tricky if the light does not screw in properly.

Maybe it's the car I own and the shape of the doors. I haven't left a review in so long, but I had to. I have a 2020 Toyota Corolla LE. It has some odd(different)shapes inside like the dashboard, so maybe the doors are odd.I worked with these things for over an hr. I had 2/4 working. Then accidentally moved one magnet so now its one because I gave up on that one too.Maybe I'm the issue because I wanted 2 on each back door for my Uber riders. I was out there with a ruler, marker and other things trying to line up the magnets to the lights. Of course it was hard to keep it straight and mark and everything else so it was never in line. I guess you need to line it up both horizontal and vertical so I couldn't find the mark.I even tried putting the magnet on the lights and closing the door then marking the spot then trying to adjust. I even noticed scapes on my frame where the magnet scraped when it closed. I even tried putting the magnet there and i think it pushed them away because it wasn't a good fit. So I moved them to other positions. Nothing worked.If it was easy for others then I'm willing to admit maybe it's the curve in my doors. I'm annoyed because I was going to buy more for the front doors, but I'm glad I didn't. I can't speak on anything else because I never got them installed

Affordable product. Great investment for safety. Super easy to install

The media could not be loaded.  Hey for the price of these bad boys and the improvements they made to the housing, you should have a set of these for every car/truck you own!!! They easily outline the doors of your truck/car and mark it easy to be seen. I do a-lot of work on boat ramps and these bad boys highlight my truck for a good 15 feet away. Saved me several time from running into my door as well (not enough coffee those mornings). The biggest change was making the cap screw on instead of pop on off. Makes it easier to change the battery. Batteries are watch batteries and readily available. 3m vehicle tape leaves no marks as well. I wish the light lasted longer on the program, but understand why to save battery life. ONLY CON. Stay away from the blue color one, too dark and very hard to see!! Red and Yellow beats colors and RED is by far the best one to be seen at night !!!

I have been trying to brighten up my car with some little enhancements. I thought these little light would be perfect. Unfortunately they were not. It was difficult to find a spot on the door where they would fit and allow the door to close. After many tries I have given up. The magnet (which turns the light on and off) was impossible to line up on the door and not be knocked off when the door closed. The magnet and the light are each held on with 2 sided tape which is useless after several unsuccessful attempts to close the door. In my opinion a waste unless you have a door with more clearance than mine.

Très bonne lumière LED, avec ca, lorsque j'ouvre mes portes lorsqu'il fait nuit, on vois très bien qu'il y a quelque chose !!Very good LED light, with this, when I open my doors at night, you can clearly see that there is something!!

No lie, one of my BEST purchases so far on Amazon. Good price, very easy to install, very bright, very flashy. SO useful and I feel like it will help a lot of drivers and cyclists that will come from behind my car. AMAZINGGGGG!

Easy installation. Lights work good. Only complaint, I wish it didn't cycle through different flashing sequences. Just wanted constant blue light on.

No charge in battery cheap quality I don't 2qnt to buy this again

Not worth
