The OEM ones are more of a molding or trim then a "guard". They are plastic and attach using 3M double sided sticky tape. While they look good, they don't provide an damage prevention……but most tail light guards end up causing damaging to the body at the expensive of saving a tail light lens anyways. As for making them fit an H3T, I don’t think they can be easily modified to fit the H3T and look good. Real Wheels make a set of the H3T.
