Yes, that's normal.. you have good power to the car, hence the brighter lights... as long as the poewr isn't spiking up into the red range your doing great.

Mark,
Welcom from another Dutch F-body adept!
Alternators on our cars often go bad because of internal heat,happens to my twice!
Last year I bought a new one as well,but I ordered a cooling device for it at JC Whitney,it consists of a modified rearend for the alternator with cooling fins and a better, larger bearing.
Summit has it also,it's called Iceberg alternator conversion kit
Maybe worth a thought?
