I installed head and aux LED's from Trucklite and couldn't be happier. Working 12 hour shifts has me riddin to or from work in the dark and in the winter, both ways. But now I can see twice as far down the road and with 180 degree view, I see them critters before it's too late. A little pricey but cheaper than HD and well worth the investment.
HD uses a fan for cooling where as Trucklite uses heat sinks. I think the heat sink is the way to go. Both have a unique look so it goes by preferance. Good luck
