H1 headlights.

Probably a dumb question but which of the two H1 bulbs in an H1
headlight acts as the high beam.The center bulb in the large round reflector
or the other bulb in the half moon reflector? On high beam I would assume they are both on and just the center bulb on low beam.
Thanks for any input.

Bottom bulb is the high beam and no they are not both on when on high beam.

Well, mine with the lo beams on and I pull to flash will turn both on but when pushed forward only the Hi's

you can rewire if you want

be SURE to add relays

about the only thing the Haynes manual has over the Bentley is a nice diagram for adjusting the H1's

ok, there are at least 3 good tidbits in the Haynes manual - I just checked the anti-Haynes rant thread started by kwm



here is my edited version of the H-1 headlight aiming diagram presented my Haynes:
