Some States require Fog Lights to be switched with the Low Beams (connect White Wire to Low Beam 12v using supplied Blue Wire Splice Connector). Some States require Driving Lights to be switched with Hi Beams (connect White Wire to High Beam 12v). Note: Some newer vehicles do not allow this connection to the OE Lighting System.
