I fitted these into the 4.5" holes in the warning bumper I have on my '99 F350. I got a spotlight. I use them as high beams as my truck doesn't have them and they are as bright as my low beam HIDs! Very pleased with the fit, finish, brightness and quality of these lights. I've been using them for a month now and they're still working. I'll post again if they fail soon!Update 2/3/17 - One of the lights stopped working today, 3 days after the warranty expired, it started flickering when I left work and when I got home , it was very lackluster Contact seller and see if they can do anything for me and let you know on customer support response. free Two thumbs up!
