The alternator is a possiblility on my old 90 prelude si before the alternator went it did the exact same thing and then one night it just cut out.

Re:lights dimming and brightening

im not a genius (not even sure if i spelt that right) but i think it would have something to with your alternator and the pulleys. cos say if it isnt running propally at a regular speed and ur fan comes on lights wont stay at one brightness. just a hunch
