I have a 2006 Toyota Prius, the hid headlight goes on and off intermittently. I got pulled over for my right headlight being out and by the time he got my warning written, it was working again. I turned my lights on and off several times.. this seemed to get them working again. I've pulled up on cars at red lights to see my light flickering at times. I only have 55K on my car, hid lamps are supposed to work 10 times longer than halogen...this should not be happening. I've read stories of some who simply replaced the bulb, to others who had to replace the whole assembly before the problem was fixed. This is discussed extensively at priuschat.com.

I have been experiencing intermittent problems with the hid headlights on my 2006 Prius for over a year. Each time I took the car in the dealer was not able to duplicate the problem. Now that both headlights are inoperable, the dealer is telling that I need a new headlight assembly. I was told that the assembly and the bulb were sold as a unit. When I investigated this further on my own and went back to the dealer I was informed that the bulbs are sold independently and that they are $312 each, and 1.5 hours of labor to install. I have an extended service package (platinum) that does not cover light bulbs. I am appalled that headlights this expensive can have chronic issues after 1 and 1/2 years of use and Toyota will not take ownership of the fact that there is a manufacturer problem here.
