I think they are #44, 6.3v, 250ma, bayonet mount. Those were in my 41-280 when I got it. I tried #47 when I restored it, but at 150ma, they seemed too dim. I also tried #44 in the dial lamp with #47 in the band select lights on the side, but I didn't like the effect, so I went with #44 all around. You can buy these from Radio Shack fairly cheaply if one of those stores is nearby, and see what effect you like best.
