Default 05 x5 help please

Hello how is everyone doing today. I am new the the BMW forums. My girlfriend has a 05 X5 3.0 and roughly about a year ago she had her alternator replaced by a friend of a friend of a friend of a family member. Well this month makes a year and she is starting to have problems now, her exterior lights dim or flash at some point and her interior lights, on her dash or regular lighting also come on and shut off at some points when she is driving. the car runs fine though with no problems. Someone told me that it could be the alternator and probably has the wrong voltage alt in there. The car has an option of 120 volt alt or 140. Can anyone help me and tell me how to check on which one is supposed to be in there and if the problem sounds like an alternator problem. Thanks alot guys for your help.
