Low Beams Only Illuminate 40' Out

What is your question?

Low Beams At Half Mast Hi, I just bought an '08 Grand Touring 6spd and the first time I drove at night I noticed both low beams only illuminated about 40' out, both are equally powerful and equally aligned. At 40' there is a definite, straight, horizontal demarcation line between light and dark. The high beams are perfect. The car is too dangerous to drive at night. I know this probably doesn't relate but seller just replaced battery so car had no electrical for a little while. Is there anything on the car that would have to be reset after that? Can anybody help? Thank you in advance.

What makes this problem better or worse?

Nothing
