Lightbulb guide.

Halogen headlight units will go straight on (they're 5 3/4" in diameter). My Autopal ones has H4 bulbs for the outers and H1 for the inners.

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.

I could not find any link on the internet to Autopal but I did find that Robsport International had GLU537 listed so I ordered a pair and now that they have arrived I see that they are obviously manufactured by Aotopal. They fitted without any problems I just need for it to get dark to check them out but they look fine. The cost at £15 which included the bulb I thought was good.

Another alternative is ones made by "Ring" and their website does list local stockist which is useful but I suspect they would have to order them in these days.

That's an excellent price, it will be interesting to see how good they look.
Chris Witor has Valeo items at £42.50 each, no lamp supplied.

I like the side lights.

Aaargh!

[Mad Mart]

Your lights look really good. If I ever restore a Sprint to keep, I think I'll do that upgrade.

I shall be interested to see what the night-time dipped & main beam intensity patterns look like, on an unlit road with cats' eyes!?!
