NAPA's Echlin line used to sell a nifty dual headlight booster relay, it takes the headlight switch out of the load carrying and so brightens up any headlights, even those old GM/DELCO ones from 1964.....

I'm sure there are many headlight by pass relays OnLine .

Another simple thing I do to every single GM product I buy is : take the light switch apart and hand polish (not abrade !) the copper contacts inside it ~ they're always dirty and this simple thing will make any headlights noticeably brighter and not co$t you anything but time and metal polish....

Old DELCO switches are usually pretty well made, I take apart the blower switches too, the improvement is instant .
