A lot of dust and grime can build up over the course of 50+ years. One day I noticed that my blinker indicators seemed quite dim. I reached behind the cluster and removed one of the bulb holders, took out the bulb. It looked a bit dull so I took a paper towel with a spritz of Windex on it and gave the glass bulb a good cleaning. The results were pretty surprising. Here are a couple screenshots from the video I took of the results. I'll let you guess which has been cleaned. This is an incandescent 168 bulb. I only cleaned the glass portion of the bulb and did nothing to the cluster or lens (Generator bulb was also uncleaned at the time of these screenshots). Certainly worth a shot since some of those incandescent bulbs might have a lot of life left in them.
