Why is my light bulb not coming out?
The light bulbs burnt out. The circuit breaker or GFI got tripped. The socket tab got flattened, and it’s not making contact with the light bulb. Some other common reasons might include: The light switch has stopped working. The Light fixture has stopped working. The wires are not connected properly. The ballast needs replaced.

What happens when you turn on the idiot light?
When you turn on the key, 12 volts is supplied to the alternator’s field windings through the idiot light. This gives an indication that the alternator’s field circuit is intact, and it also provides the current to start the alternator charging. In fact, the alternator may fail to charge if that light bulb is burned out.
