    I just put my older Boss from my GM onto a 2002 Ford F-350.I just noticed tonite that both my headlites are not as bright ( either hi or lo beam) as they were on my other truck.My problem is they are dim ONLY when the truck is RUNNING! When I shut it off and turn the lights on they are very bright!! This is a 7.3 Diesel and it has just had 2 BN HD batteries put in it.Could it be my alternator is dying or any connections loose or corroded, but I would think that the lights would stay the same if the connections were loose or corroded.Thanks in advance. (B&B- will send you some pics of the new Beast!)
