Yes the MH1 5.0 has a pretty agressive foreground limiter on them, but it can be removed. The Mini D2S does not have any kind of limiter on them. A foreground limiter is suppost to block the light right in front of the vehicle so your eyes will focus in the distance instead of right in front of you, thus making it seem like the projectors have more throw. It does not increase light output though. I'm not a fan of how aggressive the H1 5.0's limiter is either, I actually like having some light right in front of me. With the limiters on a higher truck it sort of feels like your driving in the air since it's dark directly in front of the truck, I like some forground lighting and with a 35w HID kit it's not bad, especially with a lifted vehicle.
