Bulb size??

[flatheadfan]

Need some help on this. I have looked just about everywhere for the correct light bulb size used in a '35-'37 glove box clock. I can find no references in any Ford publications. A #51 bulb fits but is very, very dim. A #55 is too big. I am using 16g wiring and have a good ground. Any ideas?

Thanks

Tom

Use the 51 you do not want heat from a high wattage bulb or you could use a LED bulb.
