Does anyone know the number for the front turn siginal light bulb. The one the auto parts store gave me is white. The Chevrolet dealer does not show it nor does my owners manual.

 

Found it. Amber 3157

 

It's handy to look up the "Sylvania Web Site" under auto and find your vehicle. You can then print out the whole list of replacement bulbs for your reference. It beats thumbing through the stupid torn up books at the local parts store.

I don't know why but the 3157NALL doesn't last as long as the 4157NALL. I'm on my 4th set of lamps in my '99 and the 4157NALL's are doing just fine for a long time now.
