To replace the light sensor:
Step 1: Shut off breaker
Step 2: Test for power at the lamp post to make sure that was the right one....................
Friend of ours went to replace his electric hot water heater some time back. He shut off the breaker labeled "Water Heater", started unwiring the old water heater........and promptly got knocked on his butt! Oops! Breaker labeled incorrectly!
Dang - I HATE it when that happens. Lucky he didn't go up in smoke.
I think he's still cursing the electrician who wired their house (and labeled the panel) when the house was built.
