Dodge Part Number 05133468AA (or 5133468AA) for the 2 lights that go into the heater/AC control unit. You'll need needle nose pliers to reach in to get the parts in/out (twist to release/install). About $2.65 each from the Dodge dealer when I bought mine - you have to remove the controller unit to get to the back side to replace them.

Might as well spray a graphite based lubricant into the cables that connect to the big selector knob while you have it apart (don't use WD-40). The knob will work better after the lubricant.
