Speaking of bulbs, Rock Auto lists instrument panel bulbs as Phillips #51 and Phillips #55 for the ignition switch bulb.

PO has used GE 55 bulbs in all sockets.

The 55 is listed as 2.87 watts and .41 amps.
The 51 is listed as 1.65 watts and .22 amps

Stock 6v system.

Will leaving the 55s in place overload the system? Do I need to order some 51s? Seems like the 55s will be brighter than the 51s but at what cost?
