That is quite the fractured beam pattern, and it's not something I'd like to drive behind. I've had all manner of lights and those areas of harsh light with sharp fractured cutoffs with odd dark gaps look like the pattern didn't come out as intended. Driving down the road, the multiple edges would create a distracting effect as the areas of light and dark bounce up and down an object, or light up a sign then bounce past it and then light it up again. The truck certainly looks different and makes a styling statement, but I would not accept such uneven lighting (hot spots, dark spots, etc) in exchange.
Also, being "brighter" definitely does not correlate to a set of lamps being "better" in terms of driving behind them. You can brighten an existing pattern to the degree that rain, snow and fog reflect back very dangerously, or inadvertently punch up the light hitting the road close to the car and degrade your ability to see further down the road. There are a lot of ergonomic concerns that go into lighting.
I'll agree with Cary that upgrading to quality bulbs in the 80s already excellent beam patterns resulted in a terrific improvement in useable lighting on the road. More power in the same factory designed pattern, preserves the high quality OEM glass lenses with vents and stout vibration free mounting, and Toyota quality assembly means years of trouble free motoring. Toss in the high beam HIR upgrade and you've got a killer system with zero mods.
On the "Fog light" discussion above. The projectors being suggested as fogs are actually a PES system which stands for a PolyEllipsoid System pioneered in Germany by Bosch for BMW. Rather than a lense (traditional) shaping the beam pattern, or the reflector (modern CAD designs w/ clear lenses) shaping it, an elliptical feature called a "mask" does the job of beam shaping. These PES lamps can serve well as low beams, fog beams, driving beams and cornering beams. The only thing they don't do well are high beams, which place an emphasis on placing as little as possible between the bulb and the air in front of your car.
So, while I like the unique appearance of this system, if the pattern shown on the wall is representative of the low beam I'd have to say it is a fractured and schizophrenic lighting pattern I would not want to drive behind when you really need good lighting. Such as an all night run across Montana, or to get home from the lake in the boonies while pulling a trailer. I'd get eyestrain watching that geometric pattern bounce all over the place.
