NEED HELP: Need info on Osram turn signal light bulbs......
 

I've read several posts by people who have these special Osram light bulbs in their turn signals that light up clear when your headlights are turned on, but blink amber when the blinker is turned on. If anyone knows the exact name of this part and where to get them for a good price please let me know. Thanks a lot, much love to the fellow S4 owners on audiworld.com.

Osram Diadems or Philips SilverVisions.
 

I prefer the SilverVisions as the Diadems are an orange/blue vs orange/silver hue of the Silvervisions.

I got them from Powerbulbs.com a while back. You'll need a new bulb base though. Stock is wedge-based 3157 while Diadems/SilverVisions are bayonet-based PY21W.

Silvervisions give you a cleaner look...we have the bulbs and the kit
 

necessary to install in stock.
