When an RV porch light works but its clear or amber cover is cracked or missing, you may only need a new lens. Start with the fixture's part number: Arcon Universal, Gustafson and Command Classic lights have different lens shapes and clips, even when they look similar. This guide matches replacement covers with the appropriate lamp families and product photographs.

How to tell whether you need a lens or a new porch light
- Look for a model or part number on the original lamp body, base or surviving lens.
- Identify the housing profile (oval or rectangular), lens colour and presence of a rocker switch.
- Choose the manufacturer's matching lens part number and compare the snap tabs before ordering.
- If the base, switch or wiring has failed, consider the complete fixture rather than replacing the cover alone.
For detailed Gustafson fixture illustrations and original model numbers, see the Gustafson manufacturer catalog (PDF).
