My Yeti is fitted with xenon lights and I keep getting a warning light on the dash when I first start up which the fault system shows as a failed right hand dipped headlight and yes, the headlight is off. However if I stop at a convenient place, turn off the ignition and turn it on again the fault light disappears and the headlamp works fine. I have checked for lose wires etc. with nothing found. Is it a feature of xenon bulbs that they can work intermittently before they fail completely (like some mains fluorescent lights)?? With the price of these bulbs I don't want to replace it just to have the same fault appear again.
