When you say random, do you mean when you're not touching the brake or power window switches? Either of those can make the headlights dim momentarily, as can a loose connection on the battery cables or at the red wire on the starter solenoid coming from the battery that ties the alternator and battery together.

It's just when I'm driving, not braking or using any switches. I'll see if anything is loose with that wire. Thanks for your time my man! I appreciate it.

I noticed on my '99 when I would leave from work every night (2nd shift), that about 10 miles down the freeway, my headlights would dim each and every night about the same time. I finally figured out that it was the alternator, commanded by the PCM, switching from a high rate charge to a lower rate charge, from the cold start-up and the need to replace the battery power consumed in the start-up.

Aftermarket stereo's and amplifiers can cause this to happen sometimes too. An old '70 Nova I used to own had headlights that would beat to the music....
