I am interested in installing a pair of headlight relays in my 1948 Chevy ½ ton truck. I am using original Guide 6V black metal back headlamps. I want to try to improve the brightness of both the low and high beams. I hope to locate a pair of working Delco-Remy #1116789 relays from a fellow Stovebolt member. I understand that modern relays are available at much less expense; I want the old-school look. From what I have been able to glean, the installation looks to be quite straight-forward. It appears either #10 or #12 wire is acceptable. Is the best placement of the relays side-by-side or stacked on the driver's side inner fender near the front lamp? Any and all insights related to this project are appreciated. Thank you.
