For my 2006 f150, there are two bulbs. Everywhere I search and even at the parts store, the only one that comes up is the #74. I am looking for the other one. I have no idea what number it is and I have looked everywhere. I ended up at the Ford Dealer and they gave me a similar bulb that was slightly larger than the 74 bulb, but it is still the wrong one. The problem is, neither the 74 or the one the dealer gave me illuminate the clusters on the far left like they should. I could not find a single bulb like it. Does anyone know the second set of bulbs that are in the instrument cluster? I am about to say screw it and just buy all #74 in LED's and see if that changes anything, but from my experience with the LED's, their spread is different than traditional bulbs and if the #74 seems to not have enough spread, I don't think a brighter LED is going to fix it either. When I got the truck, the far left bulb was screwed up, and the odometer bulb was too. I got the odometer bulb fixed, but then the high beam bulb went out and after toying with it, seems like it was just loose and the contacts were the issue. I had the same problem with the dome lights as well, and finally got that fixed. What a mess. Any help will be great.

*EDIT*

Well, still not sure about the bulbs, but just checked it at night and all seems well. I will have to ask what bulb the dealer gave me and get some more of them, since nobody seems to have them around here.
