My owners manual makes no mention of what bulbs to buy to replace the instrument panel lights. I found the ones from sylvania for the brake, SRS, etc, but not the larger one that does the gauge illumination. The bulb that is in there has the following markings:

OS 12v 10/3 and 37R and 0031 , but I couldn't cross it to anything. I've got the whole thing apart today - need help!!
