A good alternator, relays, and H4 bulbed fixtures give great light. These are reliable and available nearly anywhere.

I want to upgrade my headlights, possibly to LED. Has anyone done this? Pitfalls. I got rid of the sealed beams and went to the halogens H4's but they are still yellow and dim. After searching on eBay , I'm a little confused and then found the paid site advertisers. They have the LED type. I figure that the 7 inch round to fit a jeep or hummer would work. Any knowledge would be helpful.  I'm looking at a company called headlight experts. It has the hi and low beam led bulb .   Thanks Jim
