The headlight bucket does not appear to be sealed. Honestly the lens looks to be separate with a gap between it and the reflector. It looked to me that I outer clear lens would remove (probably after more faring removal than I would like) and could then be cleaned on the inside, and the reflector cleaned. Did I mention that this bike was outside, lying on it's side, during Hurricane Harvey.....so the reflectors appear to have some 'hard water' type grunge on them. Maybe replacement would be best.
