I recently rebuilt my rear tail light harness and just noticed that the PO had 5 differnt types of bulbs (all differnt shapes) and I can't figure out where they go or if they are even correct. Can anyone give the short answer please? I went through a ton of posts and it seems the common answers are 1156 and 1157 or 5007 and 5008? Something seems wrong with this, I would imagine there is a third one? I figured out the double contact guy
,just not sure what the other 4 bulbs are supposed to be (blue, white, red, green). My manual doesn't state either-just states A= tail lights, B=stop light etc...
Thank you

FYI, the two-fer blister pack bulbs are 2/$4.99 for 'Porsche' bulbs that the 'parts catalog' calls for (regular, not 'long life'), I don't remember the numbers though. I asked the guy at the counter to check; bulbs pulled out of the draw at the local parts store, same type, were 99 cents each. Be careful where you buy them. Seems that Sylvania likes to charge a premium for owning a Porsche. 8 bulbs for $7.92 or 8 bulbs for $19.96. Easy choice.
