A flash from the right headlight had occured. I thought it was the bulb, but turns out the ballist was shorted out. I removed the assembly from the vehicle to change the ballist and because I want to also change the lens on the assembly. When I got the old lens off, I found most of the wiring has heat distress, causing the casings to flake off. I have photos of this issue. The headlights are a high energy assembly and this unsafe condition can lead to a vehicle fire if not taken care of immediately.
