Most likely want part number VW 1059431211, Brazilian VW item. a quick search
found some here http://www.drael.com.br/loja2/index.php?route=product/product&path=113&product_id=30128
Probably available other places, try searching without the "900" on the end of the part number.
You could use a surface mount LED, much brighter and no sealing issues trying to keep out the water.
