headlights are dim! 1985 blazer

Bad headlamp ground. Could be bad sockets, or a poor connection at the body. Follow the wires from the lamps. They ground to the radiator support, one on each side of the vehicle. Usually attached to a rusted out stud with a nut. Take them apart, shine them up, put them back together.

If the grounds are good, I would go back to the question below:
A new battery doesn't mean that the alternator is properly maintaining system voltage at the appropriate 13.5-14.5 volts. Low system voltage will definitely impact headlight brightness. Use a multimeter to display system voltage with the engine running.
