Front head light failure. I’ve replaced the bulb with no resolution.

- Replacement bulb is faulty
- Electrical power not getting to bulb socket
- Fixture ground has come loose
- Bulb socket damaged or corroded
- Computer module faulty

Ask you shop to test for each of those, one by one. Eventually they’ll discover the problem.

I suspect the ballast has failed.
