My stock 13 v6 has always been hard to drive at night, it seemed I did not have light heading down the road, it was way worse than the 12 year old car it replaced....I was starting to think the Mustang lights were crap....Then I read in the owners manual how to ajust the headlights.

Anyhow, they were aimed way to low,,,they were hitting about 20 inches high at 25 feet, they were suposed to hit at about 26 inches.... Easy fix, a turn of a screwdriver!

So if you have bad lighting, its an easy fix!
