HID lights not working well when cold

my '01 E38 has the xenons. i've noticed that the bulbs dont turn on quite so easily when its cold. its usually in the 80s the majority of the year. right now its dropping below the 50s, this is the only time they give me problems. i wonder if its just the bulbs, or the ballasts. i have cheap Chinese bulbs, i have a few sets. they work well and are 35 watt. never had problems until the cold weather came around though. otherwise they work perfect. i have frequently checked on them too as i like to see that they arent messing with the wiring harness.

BTW, they will come on. but i sometimes will have to turn them on and off a few times, waiting a number of seconds in between so not to shorten the bulbs life too much.
