my bf keeps going outside to let the dog out and he says my lights start flashing on and off. I've been having a problem with my battery being drained even though its two weeks old and maybe this is why?
Is this a known problem with anyone else and what could cause this?

Very odd.

 

Which of the lights? There are sooo many LOL

In case he means the lil red one in the dash top, it's the alarm/immobiliser (PATS) light and should flash. Watch it as you unlock, as you insert key, and as you turn to position II & start car.

 

I'm gonna guess he noticed her headlights flashing. Very odd. Are they the high beams? (if so, they'd be the halogens, not the HIDs)

If its the high beams that are coming on (can't you activate them with simply pulling the turn signal stalk, even without the car 'on'?) If so, I'm leaning toward a bad stalk, shorting.

 

Could well be.
Would explain the drained battery!
