HEADLIGHTS ARE FOCKED UP

My headlights are jacked!

I had my car lowered, the shop messed up the arm in the back which set off the light in the dash. Took the car to lexus where they messed with the bars in the front and the rear driver side, LIGHTS STILL OK, but the dash light was still on. Next i took the car to a shop and put it on the lift, he messed with both arms under the car. REAR IS FIXED NOW AND NO LIGHT IN THE DASH... Here is the problem, he messed with the front and rear, how do i adjust the headlights so they are back to normal?

1 i dont want to adjust the lights themself, that seems to be the halfa$$ fix.

2 i dont want the light back on in my dash, im thinking the arm in the front just needs to be done back to stock height and i am all clear.

3 should i get another lowered car and see their lights, then look at the arms under the car, and do mine the same, or is it just the front arm that will control the lights..

4 I DON't WANT TO ADJUST THE LIGHTS from the engine bay...

CAN ANYONE HELP ME ON THIS, I CANT DRIVE AT NIGHT AT ALL, THE LIGHTS ARE JACKED UP BAD. LEXUS HAS NO FIX ON THIS AT ALL!
