hello all. I am a little confused from my manual, it says PY21W for signal bulbs and I am going to order some silver/amber replacements and they are either type 1156 or 1157. Does anyone know the conversion? I know the pegs on the socket are the difference. Additionally, I already had a reverse light go out and that is P21W, which is........??? so confusing. Any help is appreciated.
