What size/voltage light bulbs for 52' Roadmaster?

[Gordon]

I have bulbs that are 2.5v and 3.5v. I tried them both with 2 batteries and they seem to work fine. The 2.5v are brighter as I imagine makes sense and perhaps they wouldn't last as long, I'm not sure about that. I would be happy to send you two of each if you want to pay shipping which should be in the $3 to $3.50 range. You can respond with your address in a private conversation.

Most everyone of the tail lite bulbs are 2.2 volt .25 amp .
