On my HL KV-1, I removed the LED, hollowed out the headlight housing, ground off the tip of the LED and reinstalled it in the housing. There was now clearance to fit a headlight lens over it. Before doing that I gave the LED and inner headlight a coat of yellow acrylic followed by coats of silver acrylic until it was the muted yellowy-off white I wanted. Looks better than the hideous glowing nipple of the original HL design. Sorry no pics, image loader seems kaput on this board...
