I went to the dealership for this bulb/fuse, and they did not have it. The guy at the counter said he had never seen it, nor did this mechanic. He pulled up a pic of the instrument cluster and said there's nothing he can see there that was like that. He said there were only black bulb holders, no red holders.

Does anyone here know what the part number would be ?
