Update on this @##@## thing lol today had the chance to change these drls a simple job took over an hour! (Don't laugh) the plastic screw heads were rounded, so a pair of long nosed pliers and quarter turn at a time they came out. Then remove the flitch access panel, pull of the rubber cap, quater turn and with draw slowly, exchange bulbs, check they work (made that mistake once, put new bulbs, put everything back and they don't work!!!) So working and looking good. I will take night pics for you later.
