Signs of a faulty part

If you notice any of the following, the part likely needs replacement:

  • Headlight flickering or not lighting at all
  • Light with a strange colour tint compared to the other side
  • Visible arcing or damage at the connector

Installation information

Routes from the ballast to the bulb — this wiring carries very high voltage, so handle with care and ensure secure, insulated connections.

Frequently asked questions

Xenon systems generate very high voltage (tens of thousands of volts) briefly to ignite the arc — this wiring and its connectors are specifically rated for that voltage, and damaged insulation here poses a shock and fire risk.
