HVAC light bulb

Anyone know the light bulb size for the AC controls? Theres 2 small bulbs. I tried 37 and 47 but both were a tad too big and those were the closest in size at advance auto

Got the 37 to work. I didnt notice that the bulbs were slightly longer than stock bulbs. Originally thought they werent seated all the way in but got them installed and working. I since read that replacement bulbs are actually 74's but the only difference between 37 and 74 is the wattage. 37's are 1.3w and 74's are 1.4w
