5,000 miles on my '09 RT.
When I ride at night, I can see my headlights illuminating the reflective overhead freeway signs. The nearby cars don't do this, which leads me to believe that my headlights may be aimed improperly. Been this way since new.
Any words of wisdom? Could this be normal? I seem to remember that the proper procedure for aiming auto headlights is a bit involved, requiring specialized equipment, more than just a level driveway and garage door, which I don't have anyway.
I would hope that the headlights would come properly aimed from the dealer, but who knows?
Increasing rear spring preload helps a little, but does not eliminate the problem.
