    Default Headlight wiring burnt?!

    Yesterday i thought my headlight bulb had gone as there was a symbol on my dash - today my indicator started flashing fast suggesting a second bulb had gone on the same side, after checking the headlight wiring under the rubber cover i can see its charred and now very loose. it looks like its literally burnt itself out.

    Any idea how or why this has happened and what i now need to replace, surely the fuses should have covered this?!

    Normally the connector gets corroded and causes poor contact so draws more current and that happens.

    You can buy repair bits: http://www.ebay.co.uk/itm/H7-HEADLAM...item1e609a3b35

    This happened to mine. When plugging the bulb in someone hadn't located the lug correctly in the lucas connector but behind it. This poor connection eventually overheated and burnt the wiring.

    The indicator bulb was fine, it appears its earth shares the same earth as the headlight bulb.

    The headlight bulb had blown and the connector it was joined to was melted, rather nastily!

    we have isolated the cables from one another until the new h7 2 pin connector arrives and then we'll refit.

    im surprised the 10amp fuse hadnt gone.
