Standard Motor Products FPD66 Headlight Switch - Compatible with [Vehicle Models] - Durable OEM Replacement Part - Perfect for Night Driving & Vehicle Maintenance

This is NOT a headlight switch. It is a Fuel Dampener which softens the Surging inside the injection rail which is caused by high pressure fuel injection pumps. This particular model fit on my 1998 Chevy Tracker 1.6l and works PERFECTLY, so, as Fuel Dampener I give it rating of 5.
