Am I allowed to install a digital timer for the garage lights or is this against code? Obviously, if the garage lights go out at night it could be a hazard to re-light them so I am thinking that maybe this is not OK.

 

You can put a digital timer on almost anything, but I wonder about the reasoning. It would make good reasoning to install a heat sensing motion detector, which would turn the lights on whenever needed, and isn't reliant on a timer that can lose its time if the power goes off.
Now, by the same token, you can install a count down timer that will energize when you turn on the lights and extinguish them after a preset time. The only thing is it will do it every time you turn on the lights, so if you need to change the oil, the general lighting would be useless to you. At least the motion detector type, you can command it to stay on by flipping the switch within one second of turning it off.

 

I don't quite understand what you mean by "if the garage lights go out at night, it could be a hazard to re-light them".

I have a digital timer (I think the brand is Intermatic) that is installed in my garage which controls the outdoor light over the garage door. I have it set to operate the outdoor light from sundown to about 11 PM, mainly to help illuminate the house number, which is directly under the light fixture.

 

Beachboy, I think you misunderstood what I was asking. I was asking about a timer to control the lights inside the garage. In any case, it appears my question has been answered.
