Can any old red lightbulb be used as a Safelight?

I want to modify a roll of 35mm film to fit into a 1953 Brownie Holiday that is designed for 127 film. To do this I’m going to have to unroll the film from the cartridge and roll it up so it will fit in the camera. I could do this in a totally dark room by feel, but it would be easier with a little light.

Is a safelight a special kind of red light, or will a red lightbulb from the dollar store work?
