Cleaning Up a Pair of Bosch "Cat Eye" Turn Signal Assemblies from a 1972-73 Mercedes-Benz R 107 450SL







I purchased on sale a pair of "Cat Eye" Bosch turn signal assemblies on sale on eBay a week ago or so. The price was right, but I really had to scramble to take a "sows ear" and turn them into not quite a "silk purse." I knew I had to succeed, or otherwise eat crow for being a fool.

Currently there are three assemblies on sale at Ebay -- for $475, $700, and $1000. I paid $200.

The lenses had black (and also a layer of blue) paint on the top -- why? Maybe over spray. So I attacked that matter by using first some Scotch Brite type 3M paint stripper pads, followed by carefully polishing the plastic with Flitz. 

But then there were other issues! First, one screw holding then lens was rust-frozen. As were both screws holding the plastic rear access covers covering wires and the lighting assembly. But first I had to dig out debris or mud from the holes before I could get at those screws. Those screws had a very narrow cut. 

First, soak all these screws with PB Blaster overnight. then use a German screwdriver on the  German screws! Finally, I moved them.  Clean, clean clean!

This is what they now look like. I wish I could show the assemblies as purchased. Ebay photos are of too low resolution.

The upshot of all of this -- never give up, work deliberately, and preserve/restore those beautiful things from the past.


Here is how the lenses look on a R107:
