Can anyone advise me how to change the brake light and turning signal on 2012 EZ loader trailer? I pulled the silver bracket off and unscrew d the two screws but the light assembly seems to be sealed with glue (guessing so water doesn’t get in) and there is really no access from underneath. Do you have to just order a whole assemble and seal it on the trailer? Thanks so much for any help...could not find a video.
