Solution
1. Preparation
  • Gather all necessary tools and parts.
  • Disconnect the negative battery terminal to ensure safety during repairs.
2. Inspect Headlight Bulbs
  • Remove the headlight assembly using a socket set (typically 10mm).
  • Check the bulbs for any signs of filaments being broken or discoloration.
  • Replace any faulty bulbs with OEM or compatible replacements.
3. Check Battery and Alternator
  • Reconnect the battery and set the multimeter to measure DC voltage.
  • With the engine running, measure the voltage across the battery terminals; it should read between 13.5 to 14.5 volts.
  • If the voltage is low, test the alternator output by disconnecting the negative terminal and observing if the voltage drops significantly.
4. Inspect Wiring and Connections
  • Visually inspect all wiring harnesses leading to the headlights for fraying, corrosion, or loose connections.
  • Clean any corroded terminals using a wire brush and apply dielectric grease to prevent future corrosion.
  • Ensure all connectors are seated properly.
5. Test and Reassemble
  • Reconnect all components and ensure all screws and clips are secured.
  • Reconnect the negative battery terminal.
  • Test the headlights to see if the flickering has been resolved.
