Hey Bob, I thought Surf City was in California? Well anyway – if your light does not go on, and you know your light bulbs are good, and everything else is working OK then you just might have a bad switch.
A switch can be tested using a ohm meter continuity tester or a voltage tester. If you do not get a reading with either test then the switch will need to be replaced.
