Tenant leaving lights on FOREVER

[Sam Leon]

What do fellow landlords think about tenants who leave lights on FOREVER.  By that I don't mean long hours, I mean to never turn a light off day or night for months.

I have a tenant who says for security reasons she prefers to keep the exterior lights (ceiling mount) over the front and back doors on.  She says sometimes she comes back late after dark and prefer the lights to be on, sometimes she leave early in the morning while it's still bright and would have lights on.  I already have eave mount motion sensing dawn to dusk security lights at each corner but she still feel better with the light directly over the doors.

She pays for her own electric so I am not paying for the usage.

I read that leaving lights on forever can be a fire hazard but I don't know if that's a myth, or not.

The lights are enclosed, ceiling mount lights with a 60W incandescent bulb.
