    Xenon output is a very clean, white light.

    Bi-xenon I believe is more of a "rainbow" effect when you shine them against a solid wall.

    On a serious note, my understanding is that "bi-xenon" refers to the fact that the single xenon globe behind the "projector" lens in each headlight operates in both high and low beam - a shutter directs the light to give the different light patterns. In the early D4's (like mine) - this light gives me both high and low beam. The larger light lower in the cluster which has a halogen globe operates WITH high beam and is referred to as an "in-fill" light. These are generally pretty useless as they tend to point upwards (possum spotters) and cannot be adjusted without adjusting the whole headlight assembly, which in turn puts your High/low beam "bi-xenon" out of adjustment.

    I have never bothered with the "in-fill" lights as I have extra driving lights which pretty much make them completely redundant - but I have recently replaced the halogen globes in them with Stedi "copperhead" LED globes which has made them at least appear white rather than dull yellow, and does give a little more light if I am driving on high beam without the extra driving lights.

    I'm not sure how the headlights / globes are configured in later models - mine is a MY2011 model.
    Cheers .........

    Just for clarity…

    D3S (not D35) - 35w

    And yes the Osram ones are excellent.
    Replace both at once and keep the working old one for an emergency spare.

    Thanks Mike.

    My manual definitely says D35 not D3S - must be a misprint. Your comment makes more sense of what I've been seeing advertised i.e. D3S not D35.

    Headlight Flashing - only works when headlights on

    Hi,

    Discovery 4 2013 HSE

    Am I being silly or missing something blindingly obvious, but my flash only works when I have my headlights on. I've been casually 'flashing' people to let them through (the blue light appears on my dash when I pull in the left stalk) but the headlights don't actually flash unless my headlights are on.

    Is this supposed to be this way?

    Thanks in advance

    Jamie.

    OK,

    my fault for not wording the question appropriately.

    Does anybody know this fault and how to fix/resolve it?
