Yeah, to add...it's 1157. And I did the same thing, put some cheap hyper-whites on the turn signals, my only beef is that when they are on just the parking lights they are not as bright as my regular lights, but light up the same when the signal is on! I think there's a way to have your parking light match your headlights and then have them flash when you turn, but I don't know how to do that!
And cops usually don't give a s**t, unless they're having a really bad day or they pull you over for something totally different and just start scanning your car for everything illegal! Stay away from anything besides amber and white though, and maybe red(since a lot of cars have part of their tail break lights flash when they turn!?
