Nice job. I have one similar.

Just a word of caution since you mentioned the light still working. If it is an incandescent bulb, (and my guess is that it is) be very diligent about turning it off when you are not looking in. If you accidently leave the light on, it will raise the temps in just a couple hours. Ours was forgotten for less than 5 hours and was at 95 when we noticed it. I hate to think what it might have been, if it had been missed for a day or more.
