Toyota Repair: Headlights, toyota rav4, toyota dealership

Question
I own a Toyota rav4 manual transmission 4 door.  I have been having problems with the headlights. Sometimes they turn on at random times during the day or night the relay will sometimes make a sound when they turn on.  Today my car battery was dead, and i tried to turn on the headlights but they wouldn't turn on at all.  so my question is, is this a sign to replace the headlights or the relay? or could this be a bigger electrical problem?
there is not a Toyota dealership in my town, are there any other options to get a diagnosis

Answer
You could try replacing the headlight relay and see if it helps, diagnosisng electrical problems can be difficult because it requires using volt/ohm meters to check circuits and voltages and resistances. If replacing the relay doesn't help I would recommend finding a decent repair shop that has a technician with electrical troubleshooting experience.
