Default Low beam pass. side headlight on & off

Is the bulb going when this happens? It works when you start but after it's been on for a while it sometimes goes out. Dealer said they either are working or blown..I don't know if it's the bulb or something else.

halogen or HID?

If it's halogen...its the bulb. If it's HID...could be the ballast or the bulb.

If it's a halogen bulb then it makes sense that the dealer says it's either working or blown. But for HID it can easily work for a short time and go off. I've been through a couple HID bulbs and this has been the same experience for each.

if it's HIDs, I would assume the ballast on that side is going bad. Rarely do the HID bulbs turn on and off unless there's a problem with the wiring... Once they're bad, they just stay off. On and off usually indicates a ballast problem

I talked to a guy who works for a Toyota dealership in service..he's sure it's the bulb..he says the same bulb with the same issues are happening with Prius's..he says he's never had to change a ballast yet, so he doubts it's that
