Are these a dealer only item? PepBoys has no idea. AdvanceAuto has none. Their electronic bulb spec device says it is supposed to be a 194 bulb. The bulb looks correct but it is stuck in one of those twisty two ear round base things. Is a bulb supposed to come OUT of that thing?

http://www.sylvania.com/ConsumerProducts/AutomotiveLighting/LampReplacementGuide/AutoLRG-Results.htm says it should be a 161 bulb, but that still looks like just the bulb.

http://www.theherd.com/articles/bulbs.html says it is a "PC (Printed Circuit) board twist lock base".
