Watchmaker L&R Master Watch Cleaning Machine Replacement Bulb Heater Lamps. This is the #41 type. 

Fits in a panel similar to picture number 4 and 5. Unscrew the red lens then unscrew the bulb to replace it. 

I will test all the bulbs out before shipping to make sure they work properly. Please read and inform yourself clearly about this product before purchasing; I will ONLY accept returns if the bulb is in the same condition as you receive it(working/lighting up) properly.

As far as I know they will work with others L & R
