i ran across a thread on another board i visit... looking for the TINY bulbs that are socketed and mounted into circuit boards... i am not talking about the 194 bulbs in the back of instrument clusters but the same design.. but smaller... they are found in various automotive devices.. like car stereos... heater control panels.. after market gauges...

unedited text from other forum post below... including a link to see what i am talking about..












there are several socket mounted bulbs....

here is one that is slightly smaller than the PC74

edit...

PC74 bulbs is the larger size... or bulb number 2162NW
PC61 bulbs is the middle size or bulb number 5021NW
PC51 bulbs... is the smallest or bulb number 4186NW

warning... there are LOTs of variations... and i cannot tell exactly which bulb you have... or need... most should have some kind of part number marked somewhere on it... if you can remove it.. and remove a good one.. OHM it.. write it down.. measure the bulb height and diameter... with a lens.. look at the filament design.. draw a picture of the filament design.. there are pictures of the different designs on dons bulbs link above...
