my left rear light is taking some water but don't know from where, my right one is fine, no water inside.
is there any cure for that prob?
cheers

 

If its actually inside the light behind the lense & your getting the fish tank effect, then drill a small hole on the lower base of the rear lights. If its your boot gettting wet then use some sort of silicone sealent around the back of the light & refit.
