Unimount headlights too low

    I picked up a used 7.5' unimount and installed it on my truck at the end of last season. The headlights on it seemed to be aimed towards the ground maybe 10 feet in front of the truck. This makes driving at night with it almost impossible. Since it was at the end of the season last year I didn't bother with it. I'm getting ready to mount the plow up again this year and want to fix the problem. How do I go about adjusting the headlights? I see that where the light tower attaches to the frame there's what appears to be extra holes to move the light tower up. Only problem is the very top extra hole goes into the square tubing at the very top and there's no way to get a nut on the other side of the bolt. Are these holes actually there for adjusting the headlights? If not is there another way to get these aim'ed straight instead of aimed at the ground? Also has anyone successfully installed HID's into these old unimounts? If my descriptions aren't good enough I'll snap some pics in the morning.

    On my unimount there is a mounting stud to the bottom of the light, it goes through the plate and attaches with a nut. In between the bottom of the light and the frame there is a spacing lug that is used for adjusting up down. I have to either loosen the nut adjust the light and re tighten, or usually I end up cutting the stud and replacing the light then setting it before I tighten it up. Pics always help lol.

    lost me with the holes thing. usually the best thing to do is heat the nut,,take off the light, die the nut, 1/2 x 13, ANTISEEZE the bolt, reinstall with stainless washer, lock wasker and nut. should be good to go for a long time. just keep a 3/4 wrench in the truck if you wanna adj, them in the middle of the night, your good to go,

    if it is a unimount, be ready to fix the bolt after it breaks or spins off inside the headlight and you have to cut it off with a cut grinder.

    There is no way to back the nut up so

    It is not hard to do, you just drill out the 6 rivits on the bottom of the light, but a new blot in the socket, and put 6 new rivits or bolts in.
