I’ve put headlight relays on 3 different vehicles, all showed a big improvement even with old bulbs. I believe sealed beam bulbs get dimmer the older they get, perhaps just changing out the bulbs will get you what you want. Multiple companies make higher output halogen sealed beams, i have Sylvania Silverstars on my LeMans. I really like the light output and prefer halogen to HID because of the warmer color. I find the white light of an HID to be harsh.

Another thing you can do is disassemble the light switch, if I remember right it’s just a sliding brass bar that hits other contacts, just clean off the contacts and bar and lube it with dielectric grease.
