The Leedle Lightbulb in the Ice Dispenser
Frigidaire part number 5304506475 (120v, 6w.) Around $20 from various appliance parts stores. Apparently equivalent Philips part no. BC6S6 120v-12/2PK. (At least, it works in the dispenser.) Around $3 for two from Home Depot. Little bit greedy, aren't you, Frigidaire?
