Anyone knows what's the bulb on left in the red area here? The rest are ok, but the left one seems to be blown out.

 

It's the rear tail light's Parking ~ Stop lamp bulb.

Simply take out the old bulb, it should have the size code imprinted on it. If not, just take the blown bulb to your local auto parts store to find a replacement. They have charts to help ya.

 

Thanks will do that. i found instructions here - https://acurazine.com/forums/2g-tl-problems-fixes-117/how-replace-tail-light-bulb-855620/.

 

Wish I would have seen this post before I ordered chrome turn signal lights...will the Phillips Silver Vision PY21W bulbs work on my 03 tl?
