it depends upon situation where we use high beam or low beam. using high beams in city isn't neccesary and lowbeams on a highway isn't useful...
I beg to differ on the second part. When there's a vehicle coming in the opposite direction, we should switch to low beams, so that the oncoming driver isn't blinded, and doesn't pose a hazard for us.
However, on highways with dividers, such as the GQ roads, we can drive on high beams. But, we shouldn't drive with high beams while tailing a vehicle (at safe distances). The glare from the ORVMs and IRVM would definitely affect the vision of the driver in front, and result in him/her slowing down - which is not something we would be happy about.
The poll actually is incomplete. There should be options like, High Beam always, Low Beam always, High beam only when required, etc. I for one, drive with High Beams when I really need to use them.
