Slaam guys ! anybody has any experience of Prius 2007 model 10 anniversary with Hid headlights fail one light usually and when u turn off the headlight switch and on again than it works and both headlights on.????
check for loose wiring or a loose fuse. also check the bulb connectors and grips.
it can be a loose connection in HID blaster grip remove it clean the contacts with Phillips contact cleaner
Check head light relay for loose connection & weak contact.
Tbanks guys changed hids coz life of hids over.
