Help Diagnosing Newly Discovered Light Flicker

Hi all. I recently noticed that I have been having an intermittent flickering of the lights on my dash when toggling back and forth between the driving lights and headlights. It does not do it every time...only sometimes. I have never picked up on this before so I figured I would run it by you all to see if you had any suggestions/thoughts as to why this might be occurring. I recently installed a new battery, and checked that the connections were snug. I also recently pulled out the blower motor to make sure there wasn't any debris hiding in there after changing the cabin filters. Any thoughts you have would be much appreciated.
**I tried uploading a video but I guess it won't accept mpeg files, but I could send you a clip through email/facebook if you are that interested in being a good samaritan. ::wink::
