I have install and running aftermarket HID in my 2013 Legacy 2.5i Premium since I bought the vehicle 2-3 years ago. This early morning about 5:00am. I notice my driver side bulb did not turn on. When I got to my work indoor parking garage. I notice that the bulb will turn on when I have the automatic headlight on. When I actual turn the headlight to the on position the bulb turn off. This got me puzzle don't know if the cold weather is effecting the electrical current thru the wires or something else.

Then again I always have problem on my CAN-BUS HID on my Euro when it's cold outside. It like the wires has to warm up so it can get electrical current before the bulb would ever turn on.
