2 PCS Wind Powered Vehicle Lights, 8 LED Waterproof Car Wind Energy Daytime Light, Auto LED Daytime Running Lights No External Power Supply, Universal Car Accessories (White)

Do not buy it is a waste of money. I bought it and it doesn't even work I guess that's why it was so cheap.

I love it!Just another lighting accessory to add to my truck.

Well the silver paint was the first to go. They will come on for a hot second with a straw ? Must work at street speeds?!??

Crap don't work

Installs in minutes and easy. Wind wheels work when there is a lot of wind. Great idea but not practical!

These are cool! They work with just a little wind - I was blowing on them when I got them out of the package and they lit right up! They come with cleaning towelettes and the double sided sticky tape already on them, so it's very easy to install.Update: I had to come back and share this -So I put these little lights up on the inside of my grill, and also on the underside of my roof rack... Then I started to notice this weird vibration noise when I was driving so I took my car in to get it looked at cuz having a wheel bearing go bad is no fun and I've been through it before, and this new car has a warranty.... Anyways these tiny little fans can cause enough of a vibration that you can hear it inside the vehicle, and I told my mechanic he is welcome to laugh at me for this one... So if you put these over your head you're going to hear them, so don't freak out like I did!

These self-powered wind generated LED lights are an amazing idea. When I got them , they were packaged well, but the construction is all plastic including the lens. Each has a tiny fan on it that is supposed to spin and power the lights to turn on.I tested first with an air blower and then compressed air and yes when they get up to speed, the light does shine bright. However, these only worked when I put the blower right next to them at the highest speed. The fan needs to spin extremely fast to build up enough charge to light up the LEDs. If placed on font of the vehicle you would need to be on the highway with no slowdown for level of speed needed to turn them fast enough. I wanted it to light up with a lot less power needed to make the fan spin, but it seems only very fast 55+ mph will get them glowing. As soon as the speed is slowed they will stop spinning and go dark within a couple seconds. Might be more fun for a drone or remote control plane, not for a car or truck. Two stars due to not being practical but still working under certain conditions.
