I tried a search but can find nothing. Anyone know what the part # is for the bulbs? Mine are marked PC 579 but I can't find this anywhere on the web. Is this a bulb that is dealer only?

Robin...

Never mind. Got the part # from the dealer.

The bulbs in mine say T579 with J8K underneath the T579.

Actually, they both had portions worn off, so I had to compare them together to get the whole thing, so I hope theres not anymore to it.

It seems to may be a dealer specific part. The # is XU5Z13466AA. Called a bulb & socket. $3.90.
