Why do my headlights keep burning out?

Do light switches wear out?
A light switch can last for 20 years or more. Light switches don’t necessarily wear out due to age because the internal springs are not under constant pressure. Light switches wear out due to repeated use or loose wire connections that cause them to overheat and short circuit.
How do you know if a light fixture is bad?
Touch the bulb at the bottom of the socket with the other lead. Record the reading. If it’s somewhere close to 120 volts, the fixture is good. If you get a reading of zero or one significantly less than 100 volts, the fixture is bad.
What happens when light switch goes bad?
Faulty light switches can make a variety of electrical sound effects, but most can be described with one of the following words: clicking, sizzling, popping, or buzzing.

Why would a light not turn off?
The most likely error is that the wire going to the light that stays on is contacting one of the live wires. Other wires connected to it are probably supplying power to outlets and the light fixture wire may be mixed in. To check, touch each wire in turn to the circuit wire, wearing rubber gloves for safety.

- Remove the old switch.
- Replace with the same type of switch, matching wires.
- Put cover back on.
Can a faulty light switch cause a fire?
Most poor electrical connections can cause fires, including loose light switches. If the wire connections or nuts behind or on the side of the switch are loose, they may release heat and ignite other parts of the switch. If this is the case, you’ll need to replace the switch.
