What Happened
Your vehicle's headlight electrical circuits might be causing the high and low beams to turn on at the same time, which can damage the electrical connector.
Risk if Unfixed
An overheated electrical connector can cause a fire, which can be very serious and potentially damage your vehicle or even harm you.
Free Fix
You should take your vehicle to a dealership, where they will fix the problem for free by modifying the wire harness and replacing any damaged parts, such as the bulb, connector, or headlight assembly.
