Brighter Headlights??

I put H4s in Motorcycle housings in my 68FormulaS buckets and used the original headlamp wiring to trigger relays right behind the buckets. I powered up the relays from battery power through an auto-reset relay, and a fat wire.IIRC it was 10ga.
A world of difference
And you can buy the H4s in several different energy ratings.
The M type reflectors may not be legal every where. There are other offerings for automotive useage. I play nice with others and dip early, but I'm also seldom on the road after dark, and I live in a rural, low-traffic area.
