Headlight relay is stuck

If the headlight relay is stuck, the headlight may remain on or off, depending on how the relay is stuck. If the relay is stuck in such a way the the circuit remains open, the headlights will not light up. If the relay is stuck so that the circuit is closed, the headlights will not turn off.

Symptoms

Headlights Don't Light Up

The relay is used to connect two points on complete an electrical circuit between the bulbs and the battery. If the relay is stuck open, the circuit will not be completed, and current will not flow to the bulbs.

Headlights Don't Turn Off

A relay that is stuck closed will keep the circuit closed, and allow electricity to freely flow. This will keep the headlights illuminated, even when the switch is off.
