If you are going to change your lights to LED or some other super bright beam, please please please adjust them down as per Tony's comment. Remember that a Land Cruiser is higher, so the blinding effect is greater to on coming traffic than in say a Ford Focus.
Its a bit of a bug bear of mine the number of cars I drive past that almost blind me, and when I flash them to remind them to knock off their high beam, they only flash me back with a high beam so bright it gives me a sun tan.
Honestly I can't see the need for all these super bright beams, if people are worried about darkness/ animals crossing etc then driving slower is better than blinding oncoming drivers.
Maybe I'm just getting old.....
Anyway, rant over.
