The tail lights on Happy Face were pretty sad looking.  I figured the plastic on them was history and proceeded to hunt down some decent used ones out on the internet marketplace.

The old left light....pretty sad looking. 

I found a single light on ebay.  It was in much better shape than my old lights.  Only problem was it came off a '73.  Had bit of a different configuration of the lenses.

When I removed the old lights I couldn't help but wonder if they would clean up.  The cloudy plastic lenses were really only a degraded on the inside parts of the lenses.  I decided to disassemble the lenses from each light assembly to go to work on them with some Meguires plastic cleaner, aided by my handy dremel tool.

I didn't expect these results.  Here's the left light before and after.  Incredible.

Here's the ebay light compared with my cleaned up right side light.                                   The old tail lights cleaned, installed and ready for the road.
