Darrell, yes most new headlights are LHD. There are still some out there though, but hard to find. Someone in the micro car club has a good stock of headlights. If I remember correctly the lady has a blue 500. I have replaced the glass lenses with the old, bit of a fiddle but works. I have also used headlights out of a triumph, it was a sealed beam with sidelight. You need to do a bit of work to get all to work. I cut the old reflector to fit round the new sealed beam unit, then had to grind some metal off the chrome surround to get the new unit in, then used the original spring clips to hold it all together. This worked a treat hope this helps.
