The tail light lens on the Dominator was broken, but not in a very noticeable way. Those familiar will know that the lens is actually a two piece design with the clear license plate section sliding into the red tail light housing. The red section had broken at the bottom, cracking the clear section. As a result, the replacement was a low priority, and the replacement lens sat for a year. Then the recent ride resulted in the clear lens falling out.
In addition, an LED bulb had been awaiting the replacement as well. Not that this machine gets a lot of night time riding, but the increase in visibility that these "bulbs" produce enhances daytime conspicuity as well. As a bonus, they draw practically nothing in amps, so they are perfect for vintage iron.
