Could you please provide TRS's site location ? I have (2) 2014 M3's in the family; an i Touring for my daughter with halogens and a 'S' Grand Touring for myself with bi-xeons adaptives...the difference is literally day and night ! I realize that the HID's won't do the job that the bi-xeons do, but they have to be better than the stock halogens.YES!
That's why the cheap HIDs are that much worse. Because the location of the burn in the bulb is extremely different in a halogen bulb vs an HID.
This is the other main reason I always recommend the Morimoto bulbs from TRS, because they moved what they could to get the burn closer to where a halogen burns, so they put out a very similar pattern.
