Yes, regular headlights, they have 3 contacts, the middle is normally ground
and the outside 2 are high and low beams. Basically just connect your wire
up to the transformer and hook the other end to the headlight, one wire to
the middle post and the other one to one of the outside posts, you will
quickly figure out which one is bright and which one is dim, use whichever
one you like best, but bright was a little too bright for my taste and I
didn't want to blind my fish.

Another thought, for those who haven't yet soldered up and tried them:
If you really do like a softer, warmer glow, try using the low and high
beams in series. Connect your transformer wires to the two OUTSIDE
terminals, and let the middle one stay open. This puts approximately 6
volts to each filament, and they will run much lower brightness, and much
more yellow color. Also, should last just short of forever! Again, when
you're happy with the look, silicone all three terminals to insulate from
the water, or they will corrode away long before the lamps give out...
