First of all, the charge for re-aiming the headlights should be far less than $750 -- probably less than $100. I've corrected the headlight aim on many cars over the past 40 years and it has rarely taken me more than 10 minutes total to do both sides of a car -- and that was by doing it the old fashioned, more time consuming way of parking the car in front of a marked wall.
As I explained previously in this thread, it is likely that your headlights are in the default position -- they should be perfectly aligned in the default position and that is why they are "projecting together in a straight line".
The indicator light (probably) came on because the leveling system is not working and would not be able to compensate if your car is heavily loaded down with passengers and stuff in the trunk.
As I said before, there is a diagnostic procedure for the headlight auto-leveling system. It involves checking continuity, resistance and voltage on the actuators, ECU and sensors. My guess is that the entire diagnostic procedure can be performed by a knowledgeable mechanic in less than one hour.
Perhaps you need to take your car someplace else.
Thanks, sounds like the logical idea. I've got a guy in mind I can take it to.
