Halogen light stops working when cover is installed

Question

I have an under-counter halogen light (jc / g4, 12 watts) that doesn't work.

If I remove the glass safety cover (might be called the lens) from the light socket then the light works fine, and will illuminate when I flip the switch. As soon as I replace the safety cover, the light stops working again.

The cover is made of glass, with a metal circle at its outer edge. The cover attaches to the socket by three L-shaped metal arms.

If I power on the light with the safety cover attached, it produces no light, but it makes a quiet clicking noise, about 1 click per second.

Does anyone know what's going wrong here, or how to fix it?

Sounds like you have a connection problem. Ever try pushing on the light without installing cover to see if it will flicker or anything like that? This would indicate a loose wire connection.

Clicking might indicate a defective thermal cutoff sensor if the light has one. halogen lights are very hot.
