Puddle Lamp mystery (2 Different Bulbs)

[Tahoewhat]

Passenger side is correct, just like mine, from what i remember, but both of mine are like that side. In a sealed container of such. Your drivers side, not sure what that is from, maybe they broke a mirror and got replaced w older model or something. but my 05 is like your passenger side.

I guess one can start by going to the sylvania fitment guide to see what bulb is meant to be there and then start looking at what bulbs other similar trucks have. http://www.sylvania.com/ConsumerProducts/AutomotiveLighting/LampReplacementGuide/

Well, according to that guide, 2000-2006, both Tahoe and Yukon came equipped with both 168/194/T10 and 561/44mm festoon bulbs. So, I'm thinking one of your mirrors was replaced.
