Lionel 18911 light bulb replacement

Just picked up a 8911 union pacific switcher at a yard sale

Does anyone know what light bulb it takes

Thanks

Larry

I tried ,but found no lights in general for some similar switchers.Yours is a 1993. Does it have a screw or bayonet base? A screw bulb is a # 52 at 14 volts But it may be a micro bulb where the socket is a lot smaller.

Thanks Bob

It turned out to be a18v grain of wheat bulb with wires

I better stick to my postwar trains

Thanks again!

Larry

If you have the room you can go with a conventional base and bulb. I tried to find it in the jungle of the Lionel supplementals but came up short.
