As I am sure many of you know, Silverstar turn signal bulbs look chrome when off and amber when on. The amber bulbs just look wrong with the otherwise perfect front lights on the Sky. Sylvania says the Silverstar for our car is the 4157. It won't just fit. It is the universal bulb. Some OE have the tabs in the center and some are offset. The 4157 has small tabs in the center. Our cars have the offset type. The 4157 won't just push in. It might go if you force it but I won't do that. I took a small file and filed off half of each tab to match the OE offfset and they plugged right in. Just posting in case it helps someone. If you already all knew this than I am sorry to waste your time. If someone wants photos tell me how to insert them and I will take photos and try. I am a truck driver not a computer whiz.
