Did you not read my post...I've seen them cross ref'd as H16 and H7. Google it. What I read was on the G8 forums...they were apparently having problems with finding 5202's also and found an alternative or a place hat sold the 5202's.
I was answering in response to STUNNA. I've just been AFK and haven't gotten to research the cross reference yet.
