@Xulfiqar What can cause the headlight to not work, they only work on by pulling the lever to flash the lights(like pulling inwards for signal etc.) but they don't work with dimmers. All the other lights work though like tail lights, low(5W) lights, but just headlights don't work.
Relay is also checked. The strange issue is that all the three wires on a H4 socket have +12.2 volts when i switch to either low or high beam. I mean no wire is providing ground, how that can be possible, it was working fine few days ago, and nothing has been touched on it.
Car is Toyota Starlet (KP 60)
What can be the cause, bad switch, short in circuit ?
Secondly what should be optimal voltage a wiring should supply to car bulb in standard condition, 13 volts ?
