Ok dude, heres the deal. Normally when you have a signal lamp that does not bling just the arrow on the dash stats green, that means you have a burned out bulb somewhere on that side. But with all your other problems it may not be just that. This is what I would do, go check every lamp/bulb on your truck and write down which ones don't work and which ones do something funny. Cuz without knowing the whole picture it is impossible for anyone to even guess what wrong or begin to try and help you. Thats what I would do.
And you need to try every combonation like the turn signal on while pushing on the brake with the headlights on and off. Cuz you are somehow getting the brake lights up front in your turn signals which most likely is something inside the steering column at the turn signal switch. That involves pulling the steering wheel and you don't want to do that unless you have to.
