If your high beams are on or activated when your first turn your headlights on (LOW BEAM ONLY) there may be a control wire switched on the harness.
Note: This often refers to vehicles that have a single bulb for both high beam and low beam operation from the factory – such as H4, 9007 or H13.
As a variety of vehicles all use the same bulbs (H4, 9007 or H13) for dual beam operation, their wiring and internal control systems are NOT all the same.
This is a simple fix that takes just a few minutes. The 3 wire control socket that plugs into ONE side of the vehicle simply needs it’s pin positions switched. Simply “un-click” the pin from the control socket (as shown below) and switch positions. The wiring harness can NOT short out or be damaged by doing this. There are only a few combinations that will work, so switch the pin positions and retest as needed.
