Osram
7506L (21w) "Long Life" Bulb (made in Germany)(6 available) - NOT to be confused with the standard
Osram 7506 bulbs. I purchased these years ago when Osram/Sylvania
still made them in Germany and when the price was reasonable. I
now see these selling for $15+ on Ebay and ECS is selling the
standard 7506 for $5+ on their site.
This is the bulb to use in your
vintage BMW brake and reverse lights (fits newer models too).
Only 6 left in stock.
