And there are a zillion options.
I would like to hear from forum members who reckon they have purchased replacements that look like the originals from a cosmetic viewpoint.
For me the brightness is not an issue, just how they look.

For me it's the other way around, my Sprint is driven mainly at night, so brightness is the priority.
Having said that I have overdone it, brighter than most moderns now.
My concerns are both brightness (i.e. intensity) and beam pattern.
My 1974 Triumph Toledo 1300, has had 7 x 5¾ inch rectangular Lucas "Brighteyes" 60/55W H4 quartz-halogen headlamps since mid-1976; later supplemented by matched pairs of Lucas 20/20 Homofocal, 7 inch rally auxiliary driving lamps (will illuminate a white five-bar gate at 1/3 mile distance!
) and fog lamps with 55W H3 bulbs.
I'm thinking of substituting four 5¾ inch diameter Bosch or Hella, second-generation ellipsoidal-reflector quartz-halogen headlamps, as used on some 3-Series & 5-Series BMWs. With this system, the main beam of the inboard lamps is designed to overlay the dipped beam of the outboard lamps, to optimise intensity and beam pattern.
