Spot light!!!!
You will hate the flood lights if you use them on the front of the truck. Way too wide.
I have a 20" combo bar 60°/30°, and it shoots to the moon! Perfect for the slow driving in the woods, but not so good on the highway!
I will say 20° beam for front-end use will be perfect!
And consider putting at least 90 watt of lights if you want a real benefit.
I have a 120W bar, and if I can choose again, I will put a 180/240W in there!
