| Description of the problem | My current vehicle is a 2003 bmw 325i with bi-xenon headlights manufactured by zkw. Over the last year or two, the light output from the xenon headlights had dropped to the point where i get almost no noticeable illumination of the road at night (in average city levels of street illumination). I turned to using my foglamps to be able to see anything. After researching this problem on online forums, i examined the headlights myself and found that the upper portion of the projector bowls seem burned. They are made of plastic and painted with reflective paint, but the upper ~40% of the bowl is now browned and nonreflective. Apparently this is due to an inability of the paint to withstand the high temperatures generated by the xenon bulbs. Also, this seems to be common to many/all zkw brand headlights utilized in 2003-2004 model years of 3 series (e46) bmw vehicles, according to postings on the bmw-owner forums. For now, i have tried to remedy this by lining the burnt portion of the bowl with aluminum foil and can now notice some illumination of the road at night. This further argues that the burning/loss of reflective coating is what causes the loss of light output. |
