The light output on Stock is Excellent! On the U-Halo projector lights you have output is Good.
Much better then other aftermarket headlights I've installed on my Truck. The U-Halo lights have a good spread pattern which is concentrated infront of the vehicle, (Projectors) I did have to manually adjust them. Just point your car at the wall and adjust them to where the cut off line is a little above the hood. Use a phillips screw driver and turn the adjustment knobs from the top, it's pretty simple.
I haven't had anyone flash thier lights at me yet. so they must be set on my car pretty decent and I've got great visibility.
I do have a HID kit for the projectors which I haven't installed yet. Still slowly trying to research exactly how to deal with HID"S and my Daytime Running Lamps, there's going to have to be some extra modifications there from what I'm understanding!
Looking forward to seeing some of your pics this weekend!
Remember take your time, enjoy the install, and Youtube is your friend!
