Does anyone know what size or number light bulbs go into the dash cluster, brake light, for a ’72 F-250 ? I don’t need wiring diagram, just bulb information.

 

they are five bulb in the panel the two turn signal one for high beam and two that light the panel you can use 194 which is 3.8 watt or 168 which is 4.9 watt, it came with the 194.

 

1893 seems to be a pretty common bulb.

 

You cannot use an 1893 bulb in place of a 168 or 194 bulb. 1893 is a single contact bulb w/a metal end, bulb twists into the socket.

168/194 are all glass bulbs w/a 'wedge' shaped end that pushes directly into their replaceable instrument cluster plastic sockets.

The plastic sockets (F4UZ-13B765-A replaced C8OZ-13711-A & B) are available from Ford, used in gazillions of 1968 and later vehicles.

194 has 2 candlepower, 168 has 3 candlepower.

 

Be that as it may, most of my bulbs are 1893.

 

even with proper bulbs in mine it is horribly lit.
I am missing the sockets for the oil and alt lights but the rest are there.
PO probably removed them when they put aftermarket gauges under the dash.
