Its standard on the SR5's and LE's.
The turn signals can only be seen from certain angles- I guess you figured that out already though!
The puddle lamps are incandescent bulbs so it's possible they are burnt out (doubtful), but they are an adjustable option via the Techstream software. You can program the amount of time they stay on after you unlock the truck, and I'm pretty sure you can turn them off too. Have the dealer check that out for ya.
Good luck!
