On my truck I run a set of Narva Extreme lights.
I chose to have one spot and one spread beam light, but if I had the chance to make my choice again I would go with two spread beam lights. The mounts on these lights are very robust.
My budget did not stretch to HID lights, but if you can justify the cost, the HIDs definitely have a nicer light output than a halogen light, which mine are.
I agree with Alan that the Rigid Industry Dually's are a very nice light. The Dually D2 is even nicer! The price however is definitely on the high side, but that is the case for most high quality LED lights.
