4510/4512 Porch Light Operation and Maintenance

How the light at the top of the outside stairs (porch) works:

There are two bulbs inside the fixture.

When you replace a bulb, use 60 watts or less.

One is controlled by a switch in 4508.
This is the bulb on the left when you're facing the street.
There is also a motion detector that operates this bulb.
When you replace it, use a bug light.

The other is controlled by a switch at the top of the inside stairs in 4510.
