Princess Auto have a really good deal on spotlights this week a pack of 4 for $40, enough to put a pair on 2 bikes, I paid $80 for a pair for my V7 Guzzi
Ultra Performance Brand 4 Pack 4-1/2"27 Watt LED Work Lights The regular price is $39.99 each so the sale price is a real deal.
These work on 9-60 Volts DC so perfect for a 12 Volt system, Colour temperature 6,000 k 1,800 Lumens each
they may not be as sexy looking as your favourite lights but they aren't bad looking either and the price is right, even if you dont use them on a bike they would make good lights for use with a 12 Volt battery.
come with stainless mounting brackets, probably not a bar clamp.
I will attach a picture when I get them mounted but don't wait for that, the sale will only be on for this week.

I think I picked up the same one  for a backup light for my ATV when I'm plowing at night. Very bright, haven't backed into a ditch since ! Good value IMHO.
