Truck Lites have a flat cut-off on the low beam, they are suitable for both LHD and RHD. The Aussie JK's are delivered with whats called Euro spec lights, these lights have a flat cut-off on the right side of the beam, and a slight kick forward of the light on the left side.
Lights that you can't use here are Euro spec LHD lights, as they throw light forwards on the right side.
Nice trolley, The Beard.....I've been meaning to knock one of them up....I want to throw the soft top on my JK for the first time.
