Rear fog light bulb (LED cluster) - H11?

[lml999]

Can someone confirm for me the correct bulb for a 2010 A4 sedan, with LED rear lights?

Is the rear fog light bulb an H21? P16? I haven't been able to find any confirmation online...

The car is remote and I need to order a couple of bulbs before it gets here...


EDIT: The original bulbs in the rear fog spot, on my 2010 A4 sedan, with LED taillights, are H21W. The stop light bulbs are P21W, which have a larger base.

Your Voltage May Vary.

Thanks!

Someone, anyone...

Buehler?

These are obviously not LED but search “P21W LED bulbs” should get you there.

Thanks...I'm not looking for LED bulbs...just want to replace the OEM incandescent with the same.

So...the P21W is the correct bulb for the sedan rear fog?

i actually tried the LED... the stock halogen is way brighter.

The stock bulb, H21W, is an incandescent bulb, right?

Halogen bulbs in that location would melt the lens and probably the housing.

its a bulb thats all i know. sorry. but i think if you want to get the LED, go with red.

Thanks, already ordered stock replacement bulbs. No need for anything fancy in that location...they just need to turn on and off reliably...and not trigger bulb out warnings or melt lenses. :)
