4wd light on dash gone

Went to put the truck in 4wd the other day and the light on the dash did not come on. I checked all the fuses and none of them seemed to be burned out. Mechanically everything works fine just not sure if a bulb burned out or i just missed a fuse?

 

Yes, I've had a few light burn out in the dash over the past few years, not hard to fix but most require a special bulb from Toyota. Just be careful cause after I fixed the light bulb my speedometer when bad and was over 300 bucks to fix... Don't know if it was coincidence or not but happened right after replacing the bulbs.
