Coming from someone who has ran a couple different lights in my F150s. (09 and current 11). halogen, aftermarket upgraded halogen, hid bulbs in factory lights, aftermarket HID projector retrofit, and my current system which is upgraded 2013 OEM F150 HID projectors..
It depends on what you want to accomplish..
blinding on-coming traffic?
and finally.. budget?
best lighting option isn't cheap. i got used to one and then wanted more, wanted better, wanted safer.
hated people flashing me.
hated truckers flashing me after i passed them.
wanted more lighting width, to see the ditches incase of animals.
wanted better looks of the lights.
This all lead me to my current setup. with many steps in between, more research, more work, more experimenting.
