The headlight switch and or the headlight switch electrical plug may be bad. Inspect the switch/plug and you may find the plug melted.
If fuses check out fine, then check the dashlights and taillights themselves, if those check out then most likely there is an electrical problem elsewhere
Check your fuses! -I once got a ticket for 'no taillights' when my dashlights were fine -it was the fuse.
If you're CERTAIN that the fuse is good, check the headlight switch. There is a separate circuit inside the switch that controls both the dashlights and tail lights. If the INPUT to that circuit is working but there is no power out from the switch, you'll have exactly the problem you duscuss.
check the bulbs?
I would first check all fuses. My 2002 uses a weird configuration and requires several fuses to work all of the lights properly.
There is a fuse box under the hood (passenger side). I know the the fuses for the head lights are there. The fuse for the taillights is there and is labeled. This fuse includes the running lights but is not labeled as such.
Check your fuses. See owner's manual fo rlocation and identification of fuses.

Check your fuses, these are controlled by the same fuse for safety.
