Stock or not, if you are getting flashed frequently, check your aim.
It is not unheard of for factory aim to be off, particularly on Toyotas.
There was a running joke back in the 80s that the only thing wrong with Toyota 4x4s was "full time high beams"
OP, do you really want the oncoming truck driver piloting 140,000 pounds in your direction to be totally blinded by your dumbass actions and attitude? Its you that would die in that situation, not him. Food for thought.
