Well, I doubt most would care enough to go through the trouble of one, reading the manual and two, taking apart the trunk so they could get at the bulbs. I've paid attention to it myself and I can't say I recall ever seeing an 00+ with the side illuminated. But come tonight I'll be going to Advance to get this matter settled!

I checked my manual, and it is just like yours. And, the marker lights are not mentioned in the "exterior bulbs" section either.

Yeah, it is kinda strange. I was gonna go to work at it tonight, but its gotten dark and I live in a condo situation so I guess it will have to wait till tomorrow. Though I did go out and get all the bulbs. Im just gonna redo all of them on both sides. I happen to see three bonnevilles tonight, one a GXP. NONE of them had illuminated side markers in the rear. Intriguing situation.

It is amazing on how many are burned out. Good idea on replacing them all...that'* what I finally did, too. Got tired of removing it every couple of months to replace bulbs.

Your back end will look much better all lit up.

THANKS Archon I'm also anal retentive and after reading this post I checked my side markers. Guess what... they're burned out. It bothered me enough that I just went out and got some bulbs and am now going to change them. Oh yes, I didn't even know they were there

EDIT: All better now! My rear corners now light

Perhaps we'll help a lot of OCD (I like that term better ) people get all of their lights working! I went with the Sylvania Long Life bulbs that hopefully will last a bit longer.

I don't think its really about being anal, I think most people would change out bulbs they knew were burnt out. But when GM fails to acknowledge their existance in the manual and since its such a pain to remove the back lamp assembly most people just overlook it. Maybe a Poll is in order....

Who makes a 3057 LED tho ?

Try this.
