Use highbeam only when required!
when opposite car flashes , lower yours and repeat the same when they are on high beam - some morons wont listen/understand etc.
i have a friend who used to have a ikon(not holy satan , this guy sold his diesel ikon). he wanted to check milage of his car , as in pondy to chennai drive , i drove at 100 to 120 average.
so he took the driving seat , turn up the volume to 20 and 25 in a crappy sony speakers and top of that no ac(it was some what hot even in night that time) and was driving at 60 from chennai to pondy. he turned high beam from chennai and never ever bother to dim and respond to opposite car signal , though most of them flashed their lights - it was the worst ever ride for me till now , Did i mention , he also sang song along with the crappy speakers!
whole of the journey i was afraid due to the light as some one who may be blinded come straight to the car! On top of that he complains about on comming traffic light and it blind his eyes!
oops i forgot to mention - he switched back to low beam only in his home!
Look to the left of the opposite car when you drive in night. Need some practice though - You will get used for sure
