Here's a nice option for the early Type 3's.
An NOS set of fog or driving lights for the VW 1500.
These do turn up every now and then and I don't consider them overly rare - What is rare, is to see them mounted to an early car!
I don't have the balls to drill either of my good T3's to install them so these will likely remain in the box as they have done since the mid 1960's.
