There are a few how-tos floating around.
You can eyeball the three holes by locating the three tabs, then drill a 1/4" or 3/8" inch hole. Break the tabs using a small screw driver and remove very carefully through bulb socket after you break the reflector into small pieces using a pair of small needle nose wire cutters.
Not the easiest but you cant hurt your car unless you drill two far or you scratch inside of lens with wire cutters,
just seal with black silicone.
I have done two cars. Mine was a PITA (learning curve), 2nd one took half hr.
