Step-by-Step Guide to Removing a Sealed Beam Headlight

1. Prepare Your Vehicle
   Before you begin, ensure your vehicle is parked on a flat surface and the engine is turned off. Engage the parking brake for added safety.

7. Secure the Headlight
   Reattach the retaining ring using the screws you removed earlier. Tighten them to ensure the headlight is firmly in place.

8. Test the New Headlight
   Turn on your vehicle’s headlights to test the new installation. Check for proper alignment and brightness.
