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.
