I finally got fed up with repairing/replacing the lights on my little ATV trailer and am switching to the sealed units that they use in the bigger 18wheeler trailers. These fit into a rubber grommet that goes into a round hole. But how big is the round hole? My BIL had used them on a custom bumper on his truck but the shop doing the work cut his holes too big and now his lights fall out every now and then. The grommet stretches and distorts when it is over the light so I don't trust the measurement I get that way. Does anyone know the correct size hole to cut in my fender? I'd sooner just cut it once...
