Hello, thank you for writing in. There are several tests you will want to consider at this point. It would appear that there is some kind of electrical fault revolving around the headlight circuit. One thing you can do is check the power supply going to the fuse box. If this many components are struggling, the fuse box needs to be inspected. Besides the charging system, it is second in responsibility for sending the power supply where it needs to go. Check for a loose connection or dirty wires. If the fuse box passes it’s tests, you will want to perform several other tests to attempt to recreate the issue. For further diagnostic help, contact our service department.
