LED indicators on a 2003 WRX
 

will they make my indicators flash fast?

I take it nobody has the answer....................

You mean faster than a normal flash?
I suppose techinically they will, because LED light up a few milli-seconds quicker. But it won't be noticable.

Oh and next time if you want a faster reponse, post it in the right section:
