Good LEDs avoid a problem inherent in incandescent or halogen bulbs with haloing, first of all. With incandescents, this is a series of rings at varying distances that are more brightly lit, with darker areas in between. You don't notice it just looking out your windshield, but it limits your visibility.
Yes, LEDs have a sharp cutoff, which is actually caused by the semiconductor bar used to make the diode itself. A lens can diffuse or spread the light, but it takes away some of the inherent benefits of LEDs. Some LEDs are mounted with barn doors that limit side visibility or distance, but that's mostly aftermarket LEDs where the manufacturer doesn't know just how the LED is going to be positioned; a factory LED will be tuned better and be a better emitter.
The light is precisely tunable. You can have a cool white or a blue white, depending on the LEDs you get. Ford uses an ice white that doesn't hurt the eyes of oncoming drivers as much as a blue white, but has high penetration.
Bulb life has gotten much better, and replacements are inexpensive, but you should really never have to replace an LED. The costs are plummeting as well. An LED doesn't cost any more to make, now that they're being made in huge volumes, than a light bulb does. As soon as market pricing drives them down to competitive prices, it won't even be a question, and a second-hand buyer in four or five years will want to see LEDs in any truck they buy.
An advantage of LEDs is the much lower current draw. Ever left your lights on while you sat somewhere for an hour, and then had a dead battery? Doesn't happen with LEDs. You can have surrounding LEDs, LEDs in your truck bed, under-dash and floor space LEDs, and LED headlights and roof lights, and still have to try really hard to kill your battery.
Paying for them now is still a premium compared to prices in a few years, but I wouldn't hesitate to buy them right now in a new truck. Once you've driven with them, you never want to go back.
