I also failed to read the beginning of the thread properly....I was thinking mainly low beam and not blinding other people....So yes
@Ginger Beer suggestion seems to be a good one.
For burning retinas and upsetting those that fail to drop headlights.......I am personally running 2X130 W spot lights and a 42 light light bar......People seem to drop their lights reasonably quick with me flashing all those lights.....I have even upset motorists that have come up behind me, high beam ablaze.....Mysteriously my spot light switch seems to flick on as they get in front and they seem to swerve across the road, a little blinded....
I find the light bar has the light spread across the road, edge to edge and the spot lights the direct beam down the centre of the road....Perfect for lighting up your whole area...
By headlight globes....Couldn't even tell you he wattage, but having high beam on in the dark doesn't bother any other motorists...That pathetic....
So something to think about
