Spot Lights - Opinion Only!!!
I too have a strong preference is to drive during day light hours.
How ever circumstances dictated early night travel recently coming west across the Nullabour.
"Spot light blindness" is signifcant having to travel on low beam for far longer than necessary. Approaching drivers often have to travel at low beam for bloody kms because neither driver can judge the distance between when one vehicle has spots operating.
I don't think there are too many drivers like BigJon who progressively dip their lights - thanks BigJon
