This has been covered ad naseum here. But it's worth repeating. Projectors are never in any OEM application designed to eliminate light above the cutoff. Never. They are designed to shine some light above the cutoff to illuminate street signs. The amount of light reflected above the cutoff is fixed percentage of the light emitting from the properly located bulb. So, if they have the proper amount of light above the cutoff with the OEM bulbs and you triple the brightness with HID bulbs, you also are going to triple the light in other driver's eyes if you had the perfect HID replacement bulb and correctly aimed the lights.

The HID projector is not poorly designed. It's optimally designed for the bulb Toyota chose. It's just a shitty choice of bulb to design a projector around. The projector its self is quite well designed and uses premium parts. The lens is very good quality.

The proper solution is a full retrofit, but it's $$ and a fair amount of work to do. In the alternative someone could develop a simple adjustment to the cutoff - it needs to be moved slightly to adjust the light scatter above it. It just requires someone to either take very precise measurements and calculate it, or just pull apart a housing and test it. I'd guess it's in the range of a few thousands of an inch or less and you'd modify the cutoff pattern to reduce the light above it.

IMO - and it's been mentioned before, the best place for a longer range light is in the fog light position. For a well aimed HID light that will throw light the furthest down the road without blinding other drivers, you would want the aim of the light to be a slight downward slope. The slope necessary from the headlights in a 4Runner is a steep slope. So there's no possible way to aim them properly and also have the low beams shine a long distance down a road. The basic geometry prevents it.

A set of mini bixenon bulbs in the fogs would be the best setup IMO. Then re-purpose the high beams and low beams in the upper set for off road lighting. The ultra-bright LEDs along with HIDs in the OEM projector housings gives more than enough light for offroad driving. No light bars needed.
