I got those tailgate light that says the part number is 6L0 947 415. I see there are some other ones look the same but has different part number like 3TD 947 415 or 5ND 947 415 and other ones. Can I use any of them or do I have to use the 6L0 947 415? They all end with 947 415.

have replaced two stock in the trunk and added two additional on the top by similar bulbs
