I don't know if it is the same type that are in my Hitachi or not, but if they are good luck. I can find the right size at walmart or home depot, but they really should be "rough service" type bulbs. All of the vibration from the saw can cause regular bulbs to burn out quickly. I haven't found any of the rough service type, and I can only keep a normal one lit for less then an hour of sawing. I switched to an external light source for my saw.
