First, thanks to everyone who answered my post about my 2001 Honda
Civic with both headlights out.

Further investigation reveals that the high-beams work, but not the
low-beams. I replaced one bulb to see what happens, and it's the same
thing - the low-beams don't work but the high-beams do. The fuses for
the headlights look good, but as someone suggested, they could be bad
anyway. I don't have a multimeter to test them. Should I just replace
the fuses and see what happens?

Tegger - you mentioned a third, 100a fuse under the hood that protects
both sides of the headlight circuit. The biggest fuse that I can find
in the under-hood fuse box is an 80a fuse that protects the battery.
Is there one somewhere else?

Thanks
