Thanks Billion--I have been taught a trick to spray paint the top of the bulb silver so that it doesn't do the "egg yolk" effect...
Another problem--according to Sylvania's site the 7528s are clear only, and the amber ones are 1157s..same connector and everything, but the amber bulbs put out higher voltage than the clears [12.8 versus 12.0]
Will I still be OK using these or will voltage differences give me issues?
