There are a couple of light fixtures in the 5th wheel that give off such a specular light that I found it to be annoying. I scoured the internet for a "frosted" 1047 type bulb. Never found one. I also tried to see if a 12 vdc Vanity bulb would fit that socket...nope.
So I tried an experiment: I got a piece of emery cloth and tried sanding the bulb from one of the fixtures. After a few minutes it looked pretty good! Well, it wasn't much to look at but I knew it would give me a softer light. Tried it in the fixture and the light seems a bit improved.
Be mindful NOT to breath the dust put off by sanding glass.
