Switchback dual light bulbs- 2007 335i

[BimmerCoy]

Hi, does anyone know of a vendor/supplier/link, that I can get in touch with?
I am trying to locate a switchback dual light bulb to replace my amber parking/turn signal light bulbs in the front of the car. I think the light bulb part number that I want to replace, is 5200/s. I'm having no such luck finding the item for my make/model/year.

Any feedback is greatly appreciated.
