First, IF water was entering the rear lamp assembly via the twist to lock and seal port for the actual bulbs one could NOT ever blow the water out from within the lens housing without removing the assemblies from the trike body, removing the bulbs, and then simply pouring the water out! Don't believe that is what is happening!
Me thinks someone is getting water collecting under and behind the lamp assembly and the fiberglass trike body mounting location for the lamp assembly that is being blown out with either a leaf blower or compressed air. ANY water collecting there in that matter will just evaporate and do no damage.:Shrug:
