I got a sensor light with a 2 bulb fixture. The light is really
annoying. It claims that if I shut it off and back on in 5 seconds or
less, it will remain on. Well, that dont work. When I am working
outside I want this light to remain on.

I only use one of the 2 bulbs to save energy. I plugged the other one
with a dead bulb. My idea is to remove the wires going to the second
light, where they attach to the sensor, and wire that socket directly
to the power line with a separate switch. In other words, the sensor
will control one bulb, while the other bulb will be connected to a
switch only. That way I can leave the second light turned on as long
as I want.

Is this legal according to the code?

Thanks
