i am also thinking the same.
but will install the big lights on the rear bumper for such high beamers.
but problem is that if i fix them on rear bumber, then rear door of jeep wont open.
anyway, i am working on it to install such lights and will buy a sticker text also that "I don't like high beams" and will past it on rear door/glass of my jeep.
will use these lights only if someone chasing with high beams on the road.
