Assume you have the dash out or you wouldnt know if it looks good or not. The back of the dash is marked with the wattage by each bulb. Swap it with one of the bulbs that DOES light and you will have your answer.
Gone but not forgotten
The multimeter will probably only beep if it thinks it's seeing no electrical resistance. The resistance of even a cold bulb (the resistance of the filament increases when the bulb is on) might be too high to get any beeps so you might get a false reading of the bulb.
