Coach Interior Light Bulbs

[Both2Retired]

My coach uses #921 bulbs for the interior ceiling lights. Each bulb is quite bright. Does anyone use/Are there lower wattage bulbs (lower candle power; less bright)? I am not referring to LED.

I think the 921 has a 1.4 amp output. The 920 bulb has a 1.2 amp output, the 912 bulb has a 1.0 amp output and the 922 bulb has a .98 amp output.

They all should be the same size base. All are 12.8 volts.

The place I looked online indicated the 922 bulb has a different filament than the others I've listed and indicates a shorter life (life hours).

My fixtures use the C-921 bulb so I wanted to get a few spares to put away. I didn't want those expensive LED replacements but I thought I might find a smaller wattage for some use while dry camping to save power. The C-921 is 18W.

In the T-5 base which will fit the sockets, here's what 12v bulbs you can get at most auto stores:

C912, 13 Watts
C-922 12 Watts
C-918 7 Watts
C-915 9 Watts

I bought a couple C-918's for lesser used lamps or one side of a double fixture and put away the 921's I took out for spares. I bought a couple 918's in yellow also for sometime use in buggy times. It's enough light for occasional use and uses half the power.

My '99 uses a 194 bulb in all the clearance lights. They will fit in the same socket as a 921 and use only 0.27A.

They're almost too dim for reading, but are fine for moving around, finding things etc.

I replaced one bulb in every double lamp in the trailer for use when boondocking.

The 194 is a very common bulb in many cars and trucks so it is readily available at any auto parts outlet I keep a box of ten on hand for both the clearance lights and interior lighting.
