At the time, somewhere around $200 comes to mind. It's a direct fit conversion for 9007 style bulbs, so they install just like the original halogens, except that there is a new wiring harness that plugs into the factory wires, and a ballast box for each light. Very easy installation. I got mine from hidynamic.com
one more question. when did you install them and how are they holding up now. I've seen some people with one hid out. and i figured they couldn't have been that old to burn out that quick. Thanks Larry
My kit is one brightness, but there's other kits that have both. That's why I consider this my "stage 1" project. I'm planning on building projector headlights with solenoids and mirrors to give me high beams back.
