Does anyone have a list of the numbers for the lamps used in the stock 24V M37? I'm going to a couple of surplus places and I want to gather some spares if I can find the right ones. Here's one that I know of:

Signal Stat 90x turn signal switch - 3ea #307 24V lamps for pilot lights in housing. WRONG! See Below.

Are you sure they use 307's? they are a big lamp (2" long).

BO Marker, tail, hi beam indicator and instrument lighting. 1251
Stop 1683
BO driving ORD# 4511989 or ORD# 7765209
Headlamps 4860 or 4863 (You can also use the civvy 24 volt bulbs with three metal screw tabs 4800 by making adapter leads.)

Did you ever look up the price for a Wagner #4860 Sealed Beam Headlamp ?

Your right, Cuz. Nice catch! I was in a hurry and got the wrong number. 307 is what they recommend for a front marker light when using a dual filament tail light and a single filament front light. The correct number for the signal switch pilot lamps is #356 for 24V operation. FWIW the proper flashers for 24V operation is a #120.

The 307 at 21 CP (candle power) is not as bright as the 1683 which is 32 CP and is way brighter than the 1251 which is 3 CP.

We have many new bulbs that have been removed from new lights for the purpose of converting to 12 volts. I'll let you have some at a good price, if interested send me a PM.
