The headlights are on a separate circuit. Check the fuses and if that's not the problem check the headlight switch. You may need to get into the vehicle and trace back the wire that provides power to the faulty circuit.
Remember to not replace parts until you've found a real problem and you've been able to verify the problem through testing the part.
burnt out lightbulb!
If the interior and parking lights are not working on a 1999 Nissan Pathfinder, the first fuses to check would be the interior light fuse. Also check to make sure the light switch is in the right position to allow the interior lights to come on.
probably the fuse is blown.
Did you check the light bulbs? If OK, probably a bad reverse light switch in tranny.

Possibe blown fuse
Headlights,interior lights stop working.checked all fuses. I would suspect the headlight switch and/or the electrical connection at the headlight switch is faulty.
Check your fuse box, They may all run of the same fuse.
Blown fuse or bad headlight switch
Either the bulbs are burned out or the switch that activates them is not working. Also maybe a bad fuse
it's your reverse back up switch need's to be replaced that's located on the front of the transmission under the air intake piping
Check your fuses - they are operated separately
