Tail light bulb questions - Help!

[04QuattroTurbo]

So I finally got my tails tinted and installed. But while checking the tail lights yesterday I noticed something. There are three bulbs on the bottom of my tail light bulb holders. The parking or driving tail lights are ones in the middle. When the brakes are applied, only the ones towards the edge of the car illuminate with the middle one. What type of bulb is that? 7528 Dual filament? Help! TIA.

My other question is that, the closest to the inside, or the far right bulb on both taillights don't seem to turn on; I do not get a warning light on the console. When or does that light turn on?

I think the inside ones are fog lights (correct me if I'm wrong)

Turn your headlights on and pull the switch out 2 clicks and check if they turn on

+1. I only have rear fogs on the drivers side tail light, the other side I have empty.

Ah, I'll try that. What bulbs do they use? 7528?

Has anyone tried the LED replacement bulbs? I mean, its a bulb (that goes on OEM assembly) but its composed of a couple of small LEDs. I have been curious about whether buying them or not, but at $25 a pair Id rather have someone try it first...

Problem with LEDs would be that they do not draw the same amount of current (I or Amperage) as an incandescent bulb. So the monitoring system in our cars may think that the light is out, hence the use of resistors when you are using LED tails or bulbs.

Doug, I have that information, but the rear fog lights are not listed there. I know it doesn't use a H11- 55W...that's nuts. Also the sidemarker bulbs are actually incorrect in that list. I think our sidemarkers use 194a where as Sylvania has it listed as 3457, which is a much larger bulb.
