I have 7443 code taillights [stock]. can 3156 and 3157 fit in there also? I am about to order LED tails, and the 3156 and 3157 have more LEDs on a cluster.

Main question: even though my car has 7443, does 3156 and 3157 fit? and will it cause a fast blinker?

I scouldn't find the right area so I posted here. if it is in the wrong place, place move it; thanks
