Your headlights come on but your tail lights or dashlights dont come on when you turn the headlight switch on so what could it be and you already checked all the fuses?

The most common causes of the issue you describe include:
- A connector in that circuit which has become disconnected.
- A buildup of road film or corrosion inside of one of the connectors in the wiring harnesses for that circuit.
- A cut or broken wire in the circuit which causes the circuit to be "open."
- Corrosion in the light switch or a relay [IF there is a relay in the circuit].
- Corrosion at a ground connection at the light assemblies, BUT that would usually only disable one of the lights, not all.
- A defective [corroded or worn out] main light switch.
There probably may be some more causes that I can't think of now.

not sure if this is the answer but have you checked to see if you have a ground wire that is loose or the connection is bad? as a bad ground connection will give you less voltage to the headlight/headlights and they will be rather dim. check your connections to make sure they are snug.

It is possibly a switch problem. If you can get to the switch, put a jumper wire to the two contact points (hot side and ground) with the key on the lights should come on and then you know the problem is the switch. psg
