Since the first set of bulbs have went out in the vehicle at around 48,000 miles I will now be installing the 4th set of bulbs... original + 3. the bulbs in the Prius fail within 24 hours of eachother each time and it is going threw headlights around every 10,000 miles at this time. This is completely unacceptable and dangerous for a commuter vehicle.

Simultaneous failure of both low beam headlights. Vehicle was parked and shut down in a parking lot with both headlight low beams operable. Upon return to the vehicle approximately 15 minutes later, neither low beam functioned, requiring an extended night drive with high beams (fully functional). Upon examination the next day, both low beams bulbs were burned out and replaced. Prior to replacement, contact with dealer resulted in no assistance or information (they suggested it was simply coincidence.)

High intensity discharge (hid) bulb in front passenger side headlight went out. No explanation for why this occurred; it simply burned out. These bulbs should last a lot longer than 26,000 miles.

Starting on/about February 1st, 2011, any point source of light (I.e., traffic signal, headlight, taillight) viewed through the front windshield creates an optical effect of multiple images. The effect typically manifests as a triple image when the light is viewed from a distance -- one false image, each above and below the actual light. As the light source is approached, the images converge on the center (actual) light source, going from three (one false above and below) to eventually one image when the light source is very close (such as a car passing, going in the opposite direction). This effect has been continuously occurring since it was first noticed, and it occurs with all sources of light. It is most noticeable and distracting with headlights approaching from the opposite direction at night (especially a dark night on a dark road).
