Who would have thought something as basic as a bulb could become such a pest to fix? Along the the lines of Solitario, maybe orange nail vanish. I know people used to use it on faded coloured lenses to get through MOT's.
And to think you were so close to 100,000 relatively trouble free miles UKbri to thwarted by a bulb !!
All the best for the rest of your travel's.
