F-150's use H11 lows and 9005 highs. The HD's use H13 for high and low. Considering how many halogen bulbed Ford's I've had, I would highly doubt the HD's have a decent setup. But it's been awhile since I've driven an HD at night, and usually I had a plow on the front then.Are the super duty halogens as bad as the f150's?
