I just got the ViewPoint™ EVO Dual Headlight System last week....
I run the 10w light all the time, I turn on the 20w light very seldom, but I gotta tell ya, I luv the lights when they are both ON.
Reason I run just the 10w light is to save battery power.
I run both lights in heavy traffic or very dark areas.
I got my set on sale at the Performance Store for about 119.00 Great Buy!
Small NiMH Battery.
