Strong magnet. The wires were wrong in the wiring but I fixed them. I put them on and take them off after each use because with my old ones they broke the glass and took the bulb. As quality for their price, they are okay

The best and cheapest solution for trailer lights.
Personally, I remove the magnet and screw them onto the bumper. For some reason, there isn't such a cheap product without a magnet that can be screwed onto a bumper.
For use as magnetic, they definitely need to be secured with a tie wrap because they fall off at the first pothole.

As lights, they work very well. As for the waterproofing, be careful. Don't put them on a boat trailer and submerge them in water.

I needed to pay two electricians to work on them and they still remain short-circuited. The thin hair-like wires inside cut themselves and it’s the madness of the electricians who saw them! Repair and throw away, unfortunately.

I had to open the fuse and change the ground contact (it was on the right contact) because the flashes and stops were not working. As soon as I put the ground cable in the correct contact (in the center), everything worked perfectly

Product value for money. I don't think they are waterproof because one has to take them off when entering the sea.

One flash does not turn on, probably wrongly connected, so what if they have strong magnets if they don't work.!! Stay away !!

Half of the lights were not working, I had to open them to see the problem, the cables were close and disconnected.
The magnets are quite powerful.

Honest product, it does what it says and with great accuracy. Its quality is quite good and its cable is long enough to cover even large areas.

The cable is thin, the magnets are not sure they will hold during a trip, they need to be attached to something else, and they are not waterproof.
