Do factory xenons lose effectivness of lights

Do factory xenons lose light after a few years? or is different manufacturers headlamps that make a difference.
i was in a brandnew mercedes e class and the headlamps brightness and reach was way better than my 2011 audi a5.

If i replaced the oem bulbs would that make a difference?

Yes. Much like any bulb they lose effectiveness although xenons do last longer. I replaced them on my old car which was on 65,000 miles and noticed a big difference. Didn't need to change the ballast, just the bulb. Gives you a choice of temperature too

replacing with something similar to this http://www.ebay.co.uk/itm/Authentic...658216?hash=item3d11900ce8:g:fFwAAOSwll1WvgAU

That seems very expensive. You'll get them a lot cheaper than that as long as you get aftermarket ones

Yes they do fade a bit. I bought Philips Xtreme http://www.powerbulbs.com/product/xenon-x-tremevision-d3s-42403-single they're near perfect. Expensive, yes but all D3s bulbs are
