    My stock hid headlights don't seem to be any more effective at lighting the road ahead than halogens, in fact when the main beam or foglights are on the xenons light is almost lost, yet when I see the growing number of other cars on the road with xenons they're almost blindingly bright. I've fitted new oem Philips lamps but the difference is negligable. The light throw is good they're just not that bright. Side by side with anything new with hid's and it's almost embarrasing. Is any body else of the same opinion that the stock lights are poor or any advice on what to check with mine, cheers.

    I sometimes wonder if mine are on at all.. the only good thing about them is the self levelling.

    I had a vauxhall Omega Elite in 1998 that had fantastic factory xenons, nothing has come close since.

    Looks like I'm going to have to start modding then .

    I think the self leveling is good too,especially on start up,but occasionally in fog /snow I'd prefer to be able to manually drop them.

    I decided to have a closer look at the lights today, with the intention of cleaning the internals of the projectors and this is what I found. You can see the projector has overheated to the point of cracking and the reflective surface is now charred and black. Both driver and passenger lights are like this. My car has the factory fitted xenons and hasn't had high power lamps fitted,just genuine replacement lamps (philips 85122) . I'm quite surprised that the reflectors are plastic as I would have assumed that xenons run quite hot. If your lights seem dim maybe pop the lamp cover off to see if yours are the same. It doesn't look like the reflectors would be available seperately, anybody any idea how costly new headlights are?

    I'm sure OEM replacements are going to be extortionate.

    Maybe you could buy non Hid type and convert them using the factory parts from the old headlight ?

    I know this is an old thread, but hey, I did a search...

    Has anyone found a way to improve factory HIDs? Mine too are quite disappointing.

    First thing I'd like/need to do is raise them a bit. I know they're self levelling, but is there a way to raise the 'base line' so to speak? On country A roads, which I do most of my driving, they are frankly dangerous on dip and high could do with being a bit higher too. By contrast, when I flick to main beam (Osram Rallye 65w) it is like day from night... I really was expecting more.

    I assume they're 35w? I also assume to upgrade to 55w hids I'd need to change the ballast. is this do-able in the factory setup?

    Any other ideas?

    The projectors are possibly burnt out, if you wanted to split your headlights i can supply you a projector upgrade which will make your xenons perform as/better than a 2014 car.
