In an effort to boost headlight output, I was considering the installation of relays on my '68 Cad. I was going to install H4s, but was afraid it would be too much for the headlight switch. Plus, if I can achieve 13.5 volts to the stock lights after installing the relays, I may not have to change out the lights. Anyone have any experience with the end result? Thanks!
