Wow, thanks to you all for your replies. Let me answer your questions.
Firstly, forester 2002s. You are correct about DRLs in Australia. Matter of fact, after checking on www.howsafeisyourcar.com.au I found that the 2010 Outback does not have DRLs even as an option. The order of lamp illumination is: first setting, parking lights. This illuminates small quartz lamps in the corner of the high beam housing. second: low beam headlights are on. Third and last setting is the auto function. In both setting two and three the HID low beam lighting is the same intensity. I drove the car last night and it may be my eyesight, but since I last drove at night, I believe that the low beam was even duller than before. So, F4me, you may be right about the lifespan and deterioration of the lamps, but these lights have been, to me, unacceptable since day one. Co-incidentally, I have to return the car to the dealer due to a recall about the wiper motor, so I will take your advice mt, and hit them up for it. Don't like my chances, as they did nothing while it was under warranty, so what would compel them to do it now. However, will give it a go. Will keep you all posted.
Cheers.
