2001 TJ light problems
 

Headlights won't turn off, high beam indicator won't go off, taillights won't work, signals won't work. Have checked several fuses. What could it be??

Morning,
Sounds to me it may be a fused (as in seized open or closed) relay somewhere. When trouble shooting ANY electrical problem I always start with the simplest/cheapest things first. You're off to a good start with the fuses. Other suggestions would be: check for corrosion in connectors, check your grounds, check for worn/broken wires at friction points.
Hope you find the problem and you have a warm place to work. It's starting to get chilly in VA this time of year.

what have you done to it recently?Anything?Nothing?
I ran into a similar problem on a friend's Jeep,the problem stemmed from when he connected an electronic brake for a trailer-skinned a wire he shouldn't have and caused an intermittent short circuit.
