Big rig lights
X2 on this. I have white ones mounted on the underside of my step bars, tapped into the done light wire, for puddle lights, and haven't had a problem with them falling off. Although this will be my first winter running them. They are super bright, and like you said, cheap.
I had them on my 00 150 they lasted for 2 winters up on there. they where super bright and I never had a problem with the wiring or anything also they where pretty easy to install and the kit gives you clips to hang them with. I will be putting them on my 05 soon.
