Convert Headlight RHD to LHD
Posted: Mon Feb 23, 2026 9:40 pm
A pointless topic for this forum: how to convert the headlight beam pattern from RHD to LHD 
The Lotus's lighting is very weak, after investigation, my headlamps still have the RHD mask, in France for the equivalent of the MOT, it’s ok if the light beam is down.
Unclip the small metal plate
Now we trace the metal sheet onto paper
Mesure the angle
And report the same angle on the opposite side, cut the grey zone.
Cut the profile on an aluminium metal sheet of 0,5mm, the most difficult is the 2 little tabs
Lock the small tabs, do the same job on the other headlight.
