Need part number for lamp (light bulb) for Kenmore microwave 665.69646992?

The light that illuminates the stovetop below my Sears Kenmore Elite microwave range hood, model 665.69646992, has burned out. This consists of two very small bulbs -- lamps in parts lingo. I asked the Sears parts finder service, and they sent me an utterly useless link back to the Sears parts finder for the model of microwave.

Surely these bulbs are the most commonly-needed replacement parts for this appliance. Has anyone else replaced this part? Can you share the part number so I can order it? Of course, Sears doesn't carry the part at the local parts store.

By the way, the oven was made by Whirlpool. I know this because the microwave was recalled due to a safety defect.

Thanks,
