Where do you remove the ballast from a headlight?
The connector is what is such a problem to remove past all the obstructions inside the headlight assembly. Note the corrosion from the water inside light assembly. To start, remove the 4 screws from the corners of the cover and remove the cover. The ballast is mounted on the back side of the cover.
Where is the ballast on a HID lamp?
The ballast is mounted on the back side of the cover. Flip the cover over, and remove the black wiring connector (already removed in photo below). This connector supplies 12 volt power to the unit which is then converted to the 25,000 volts driving the HID lamps. Remove the 3 screws holding the ballast to the cover.
Why does headlight water lead to HID ballast?
Honestly what was Toyota thinking, putting the most critical and expensive component of the HID system in a location where when there is a breach in the headlight seal the water collects around an electrical component generating 25,000 volts when it is energized! No wonder HID’s in Gen II’s have such a reputation for failure.
What causes the ballast on a car to fail?
If moisture collects in the assembly it ultimately ends up puddling around the ballast which then causes corrosion and ultimately failure, as was our case.

Is the headlight on my car not working?
OK Headlight out – Right Pain in the a** but got it out (only releasing bumper along top, end & underneath), swapped over ballast and tested before re-assembly. Problem remains, exactly as before, check right bulb and confirmed its not working. The light movement functions fine when switching on headlights and all other bulbs work as they should.
