dim brake lights are almost always a ground problem. remove the trunk panels on the backside to expose the taillight wiring. there should be some ground wires attached to the body of the car somewhere by the tail panel. the lights are not grounded through the housings (a lot of older cars were). if all else fails, get a multimeter out and determine which color wires are grounds (most likely the black ones), and run your own ground with an inline tap (from radio shack, etc). use a crimp-on ring terminal on the other end of the wire, and either screw it down to the body or use an attatchment nut for the taillight housing for ground. should work... it's not usually a positive power problem.
Check the ground wire to the brake lights.
Your alternator is not working properly
A device to gradually dim the brake lights after they are held on for over a set period of time.

Dim All the Lights was created in 1995.
a common cause of rear lights staying on is a bad ground. Have someone watch the brake lights while you turn on the park lights. if the brake lights go out, or dim noticably, seek corroded, or broken ground wiring at or close to the tail light sockets. another easy reason is the brake switch is out of adjustment, or faulty. set your cruise control, and apply the brakes. i am not certain, but most systens use the brake switch to turn off the cruise. in your case the cruise may not engage. Good luck. hope this helps.
Bad ground or bad switch
You should dim your lights as soon as you see their lights.
They have a bad ground, if you notice all the other lights back there will be dim also. You need to track your ground wire or check your light bulb socket and make sure its getting a good CLEAN ground.,

Your headlights may not dim because you don't have dimmer lights. Dimmer lights can blow and leave you with just the high beams.
Well when you are driving the alternator is at a constant speed then when you slow down the alternator sort of skips a beat causing the lights to dim!
