I am sure there are many of you guys and girls that would like to have brighter headlights. The 60's Chevy trucks electrical systems are very much outdated. By installing simple 12 volt relays into your headlight electrical system you can achieve headlights that are "night and day" compared to the stock brightness. Check out this link at

I have been installing relays into all my projects for several years. I even installed them in my 94 Dodge Diesel headlight wiring......
Relays are very beneficial for a good running electrical system. Excellent for electric fans, air ride compressors, radios, amps, HEI units ect.
