Bare bulbs on a light bar collect dust. Occasionally I rinse them with water and I do think it makes a difference in the amount of light. Especially on light bars with 10 and 12 bulbs: Dust × 10 and dust × 12 can be a lot of dust, and it just gets baked on with the heat from these incandescent bulbs. So does it make a significant difference in the amount of light?
Maybe.
Maybe not.
But I’d like to think so. ¯\_(ツ)_/¯
