Dipped headlight is working again, without replacing the bulb. I read in the translated manual that these HID bulbs can stop working when the inside of the light cluster has become damp & disturbs the 'range of operating current ' Dipped headlights suddenly not working has happened to me before - I thought perhaps a loose connection but not so. Have other owners had this problem? Very disconcerting when it happens. It was a wet night last week when this last happened, but only on the nearside light. Luckily I don't drive the Alphard much after dark.
