Buoyed by the fact I got the turn signals working, which was a bad connection to the multi-plug (yes, there is one multi-plug on this car!), I decided to experiment with the front lights.
The front lights worked but were rather dim and only illuminated in the center of the glass. I started by rubbing the reflector down. Someone had painted it black- reasons unknown. I guess that it was either chromed or painted white from the factory.
A rather half-hearted effort, admittedly. However, the reflectors are very pitted and will never be perfect.
I used some “Shiny Silver” spray paint. It is a dull aluminum color at the best of times. Still, masked the car up and painted the reflector.
A significant improvement. Pulled all the paper off and reassembled the light.
The difference is significant. I think I shall have to take it apart again and redo the rest in silver, but I may also have a go and experiment with plating.
The turn signal is now very visible from a distance. The other side is not as good, as the bulb holder has been replaced and the new one welded in place. It is slightly off-center, meaning the light does not illuminate evenly, but I think improving the reflector will help, regardless.
