Bulb Chart

I just completed refurbishing the gauges on my '54 3100. The truck has been converted to 12v. Here is info for it:

Ignition light, gauge cluster, and Speedo lights come on when the tail lights are on.

One bulb in the ignition switch housing:
6v = #51: 1 candle power, 1.7w @ 7.5v
12v = #53: 0.7 candle power, 1.7w @ 14.4v

Two bulbs in gauge cluster:
6v = #55: 2 candle power, 2.9w @ 7v
12v = #57: 2 candle power, 3.4w @ 14v

Two bulbs on each side of speedo:
6v = #55: 2 candle power, 2.9w @ 7v
12v = #57: 2 candle power, 3.4w @ 14v

Two indicator bulbs in speedo. Both bulbs are surrounded by 1/2" ID cardboard tubes with colored plastic lenses. Red for high beam, green for turn signal. My lenses are gone, so I painted the bulbs with a light coat of red or green rattle can paint.

Top lamp is for high beam indicator
6v = #51: 1 candle power, 1.7w @ 7.5v
12v = #53: 0.7 candle power, 1.7w @ 14.4v

Bottom lamp is indicator for factory installed turn signals, or for after market turn signals with lamp connected to 3-prong flasher (center terminal on flasher, I think) '54 was the first year with an indicator lamp for turn signals.
6v = #51: 1 candle power, 1.7w @ 7.5v
12v = #53: 0.7 candle power, 1.7w @ 14.4v
Later model 12v trucks used a #57, the lower wattage #53 in my truck is plenty bright.

Suggest that you install all new bulbs while you are at it.

My truck is a chevy 66.

The factory service supplement for 1966 trucks has the wiring diagrams. If you want the complete service manual you will have to buy the 1963 manual as well.

Also here's a link to the diagrams only;
