photocell supervision?

Already heavily invested in mfi. Have a need to monitor a light source (hvac UV light) for failure. 

The UV system I am leaning toward (Honeywell) has a light pipe on the outside of the unit that shows that the bulb is operating. When the bulb fails, the light pipe goes dark. 

Anyone currently have a solution for alerting when a light goes out? (via photocell?) 

The location of my furnace, and especially where this unit will need to be installed is in an out of the way location that will not be readily noticed. So automation is helpful.
