Headlight suggestions

I want to upgrade my 512TR headlights to the brightest thing available, like on modern cars. Many years ago I had a custom headlight harness fabricated that uses the headlight switch on the steering column stalk to activate two relays which then bring full power to the lamps. Aftermarket lamps were installed but I can't remember the type (not LED, not halogen) and they are getting old. Same for me, so I need the most light I can legally install.
Any suggestions?

 

I finally found the info from March 2009:
The wiring harness from Susquehanna Motor Sports (through Daniel Stern) was $168. Totally worth the $$$. It is beautifully constructed, custom for your vehicle, includes relays and fuses and is a plug-in with no cutting.

The lenses were Cibie CSR (Complex Surface Reflector) units that fit in the original hi and lo beam housings with no fuss. They supposedly "focus" the light reflected to the side back in front of the car. They were expensive, like ? $55 each (x 4)

The fog lights were H3 Osram Night Breaker +90 Ultra High output 55w. They plug in without modification (the fog lights in the 512TR are already on a relay). $53.61 for both (shipped).

The Hi beams are Narva Rangefinder (HIR) H1 +50 Super High Output 55w. $31.50 for 2 bulbs.

The Lo (dipped) beams are Osram Nightbreaker (HIR) Hi +90 Ultra High Output 55w. $41.18 for 2 bulbs.

My headlights are crazy bright, way, way bettter than stock GE bulbs. These replacements are HIR (Halogen Infrared Reflector) technology, and NOT "Xenon" (more properly HID - High Intensity Discharge), which would require extensive rewiring and fabrication for not much more output.
