Am considering following modification this winter: On rear boards: Burn positions 2 and 4 as taillights Burn positions 2 3 and 4 as brake lights I'd leave boards intact w/ OE single filament sockets -- insert mod before card edge connectors. Positions 2 and 4 would be switched with a relay triggered by 3 itself. My question: would constant burn on 2 and 4 generate too much heat for the bezels? That may be reason for extra large 3 (and a noticeably smaller bulb). Bill Robertson #5939
