Common Problems This Part Can Address

• Headlights that do not switch on or off correctly
• Intermittent lighting control caused by worn internal contacts
• Electrical resistance from aging switch components
• Broken or unreliable dash-mounted headlight switch operation
• Fitment issues when replacing a switch with the wrong connector or terminal layout

Installation Notes and Tips

Verify the vehicle has the listed Visibility Light Group and confirm whether it uses or excludes auto light on/off delay before ordering. Match the 1 rectangular female connector and 7 blade male terminals to the original switch before installation. Because this is a direct, snap-fit style part, proper alignment with the dash opening and connector orientation is important for a secure electrical connection.
