The headlamps keep switching off intermittently on my 2004 Toyota Prius. This has been happening fairly regularly over the last year, but last night (8-2-2011) both headlamps failed at the same time when on a dark, windy road causing me to almost crash into a tree (I couldn't see anything without the lights). When I switch the headlamp control on and off, the headlamps come on again, so it is unlikely to be the bulbs. Sometimes only one lamp goes out, sometimes both; but they are failing very frequently and causing me a major safety concern. I have researched this issue online and there seem to be many consumers that have the same issue. Please help.

Less than normal wear and tear; only have 32K miles on my 2004 Prius. The passenger side headlight blinks off or doesn't light in the first place every time I drive it. Nothing done to repair it since this particular component isn't not under warranty that I'm aware of.

My daughter owns a 2004 Toyota Prius with hid headlights. The lights fail one at atime or both at the same time. They come back on usually by turning the switch off and then back on, except when she was driving at night in the fog, and they did not come back on. She had to park and spend the night beside the road, until daylight to continue driving home. She has contacted Toyota about the problem and has found out that the bulbs cost $350 a piece and requires extensive dismantling of the car to install them. This meaning that a $1000 dollar expense for replacing the bulbs, not knowing if there is a deeper seated problem with the power supply to the headlights. I was just wondering if their has been anything done about a recall?

Right headlight intermittent took it to the dealer said I don't have a problem functions perfectly. Well I now have a ticket to prove other wise. Turn the headlights off it will come on then die. Now the light just plain doesn't work. Dealer wants $886 to replace. Sounds like a dealer recall problem with a majority of Prius hid systems. It is also a safety issue.

Toyota 2004 Prius - passenger-side hid headlight went out. Dealers want about $650 to fix!!! (includes having to take the bumper off.) the cost is an outrage. I can't afford it. These bulbs have apparently failed on many priuses, so dealers are cashing in.

While driving (or sitting idling) one (or both) of the headlights will go out. I have verified that the light goes out completely and does not just dim. When only one headlight goes out, turning the headlight switch off then back on will re-ignite the headlight. When both headlights go out, they will not come back on by turning the switch off and on. It takes 4 or 5 attempts at switching off/on before they come back on. I must drive at night time, and this problem causes me to be plunged into darkness suddenly while driving (a very dangerous and frightening experience). The dealer did not know the cause of the problem, but was very willing to sell me 2 headlight bulbs for $790 and if that did not fix the problem, come back and buy 2 control units for $950.

Driver side hid headlight goes out, but reignites (most of the time) after headlight switch is turned off and then back on. Recently, the drivers side light was out (and would not reignites), and the passenger side light went out as well, leaving me without headlights. The passenger side light did reignites after turning the switch off and back on.

Passenger headlight on 2004 Toyota Prius goes out intermittently. I have noticed this about 8 times. On one occasion I was in a vehicle in front of the Prius and the headlight went off after 15 minutes of operation. It came back on after the vehicle was turned off and restarted. I took it to the dealer today, expecting a diagnosis and they put in a new hid bulb ($324). I had them save the old bulb because I am doubtful a new bulb will solve what appears to be an electrical short circuit problem. Not having both headlights operational is a safety problem that needs to be addressed with the root cause ascertained and repaired by the manufacturer.

The contact owns a 2004 Toyota Prius. While driving in any type of weather, one headlight would dim followed by the other. However, both headlights could dim simultaneously. The failure occurs intermittently. The vehicle's speed was not a factor. During the failure, all of the other lights were operational. The contact has had the lights repaired due to safety concerns. The current mileage is 90,000 and failure mileage was 70,000.
