Are your headlamps pointing down too much due to damage to the axle sensors that measure vehicle pitch? If so then all you really need to do is bend the brackets that hold the sensors back to somewhere close to their normal position, and then reaim your headlamps.
All the sensors do is send a signal to an ECU that calculates whether the car is pitching, which then adjusts the headlamps to stop them dazzling oncoming drivers. If these brackets have been bent out of shape then the signals from the sensors (basic potentiometers) will have changed, and hence the ECU will think that your car is permanently nose up/down, and hence set the headlamps to an incorrect position.
You could however just reaim your headlamps to a correct aim and not bother sorting the brackets but this may lead to problems with the levelling system being permanently biased to one side of it's operating range and the posibility of it operating outside its adjustment range. This can lead to the reflectors in the headlamp being wound off the end of their adjuster screws which would then require new headlamps.
Hope I have picked up on the right meaning of your post and this hasn't just been a complete load of nonsense and good luck
