Had a wreck-replaced front clip, final phase is headlights. It's a daily driver so put salvage yard stock housings and some old Sylvania's in to be legal. Getting by with a pair of LED fog lights for back roads. Of course I'd like to upgrade. Hopefully to an LED that is not obnoxious to other drivers, or having to overhaul the whole system. Kind of limited on time, but performance and quality are priority. My thought is to convert from 9004's to 07's or whatever else that will start me out with a better bulb. Then it's between halogen and LED's, and reflectors or projector housings. I have the harness to go to quad bulbs but I believe the computer needs to be flashed. If two bulbs can do the job near as good as four then I'll stay with duals. I see some have been trying t o figure out the same problem. No need to start a new thread if there is a current one, but this is an evolving subject, I see new technology about every time I look. I'd appreciate anyone's advise. I will post my progress and results with pics if it will help anyone else. Thanks in advance.
