lmao niccceeee , i heard throwin in gold fish in you tank adds fuel efficiency...and having a salt water intake adds a good 20 hp!

 

my tail light looked the same , it was the one with the key hole. i took all the bulbs out to let the water dry out . I re-fastend the bolts holding the liht down and have not had any water in them since ... mazda did not tighten the freaking bolts enough to seal the light to the rear end causing moisture build up . From what i have seen is only the back light with the key hole has this issue try this. If light has scratches on it screw it take it to mazda with the water build up and they will order a new one
