Classic/Antique Car Repair: 6 volt flasher, Flasher not working

Question
Dick
we are working on restoring a 39 chevy firetruck,  we are going us for a parade truck,  the oem flasher unit for the front red light is bad, and we can not get a regular 6 volt flasher to work,  can i get an oem unit for this.  the one we have is about the size of your little finger with a stud in each end.  any help would be great

Thanks  Jeff

Answer
I'm shooting in the dark here, because I am not a truck guy, and I certainly know nothing about firetruck emergency lighting.  The only reason I can think of for the regular 6 volt flasher not working would be something to do with the current drain of the red light - it must be much too much to ask of the normal flasher.

An electronics guy could design a relay operated flashing light power unit for you quite easily - ask at your local Radio Shack for the name of someone who plays with electronic devices - they should be able to give you someone to help you out.

Sorry I can't be more help myself.
