Need bulb for Guest Remote Controlled Spotlight

[rocstar]

I have a spotlight that I believe is a Guest brand, with a remote joystick control. It came with the boat. I need a replacement bulb. The bulb is 4.25" in diameter and it has 3 leads. West Marine has the new units in their electronic catalog, but not the bulbs. Anyone know where to find one?

After a little searching, I believe this is a GE 4700 Incandescent bulb. It is 100W at 13V. I found a couple of places on the web that sell them, but I'd like to find a local store, such as an auto parts store.
