I was double parked and had my hazards light on as well as my interior lights.
I noticed that the interior lights were blinking slightly along with my hazard lights .. is this wierd or what , or just the way GM make their trucks..
Well if anybody has the same problem let me know ..

I've never had the problem of double parking!
When you made this observation, I assume your engine was
not running, so the draw to the flasheres transfered to the interior light circuit and each time the flashers were lit by the battery your interior lights dimmed, not a biggy. More surprising with the engine running and the alternator powering the system, but still not a problem.

I had a GMC 4x4 a while back with underdrive pullies (slows down the AC and alternator), and
everything would dim with just a turn draw signal when sitting idle at a stop with the lights on, that was extreme. I'll go to lunch and put my flashers on.
Just the nature of the beast as far as I know.

Could be a weak alternator!

Most likely a voltage regulator that is not performing up to spec.
