OK..
So I've done a lot of research on the boards on this whole Brake Light issue that seems to come up repeatedly, yet I still can't find a conclusive answer on a good diagnostic approach for determining the full cause of the problem if it's not low brake fluid.
My fluid is above the full line, and the brake light comes on in my truck only when I first start the vehicle up and release the e-brake. I am able to usually jiggle it and push the handle all the way into the retaining nook and it will go off.. but then come back on again until I jiggle it just right.
From what I can tell... most people say that this requires a parking brake/e-brake adjustment where the cable attatches to the lever.
However....
the site seems to recommend that if your parking brake is fully engaged with between 8 and 14 clicks... it should be fine. I counted the number of clicks that it takes to fully engage my brake, and it's somewhere around 9 or 10.... yet the brake still feels loose when not engaged.
I want to get under there and adjust it as soon as we have another good weather day(if ever), but now I'm a bit concerned that maybe it's not the adjustment on the cable.
I guess I need to tighten the E-Brake cable according to this?

... or do you think that it is actually a problem with E-Brake sensor in the cabin?
One additional tidbit of info... When I first release the E-brake, and then step on the brake pedal, my brake pedal feels like it has a little bit of free playin the first 1/4" of travel(Just the first time i push it), then it feels fine after that... which makes me think that it could just be that pressure had to build up in my master cylinder. I figure I'd throw that in here, in case it has anything to do with problem diagnostics/resolution.
