Trying to identify an RV porch-light lens from a broken cover? The housing's manufacturer and model number are more reliable than the colour or approximate width of the plastic. Compare these known Arcon, Gustafson and Command families, then follow the exact part link to examine the replacement.

These are family-specific references. The old lens's tabs, curvature and fit should also be compared before ordering.
Identify a missing or cracked cover before replacing it
- Photograph the fixture, including the switch and remaining plastic tab positions.
- Read any part number from the old lamp body or packaging and check its family in the chart.
- Measure the loose lens itself if available; the lamp's overall width is not the lens width.
- Inspect the fixture mounting and condition, then select either a matching lens or full replacement light.

The product listings show the relevant components and their current condition and availability. Verify the lens and fixture number before selecting an item.
Recognize Arcon Universal rectangular components
Check for the Arcon Universal rectangular housing before ordering part 18106. The examples here include white and black bases, plus both switched and unswitched lights.




Recognize Gustafson rectangular components
If the lamp is a Gustafson AM4017 or AM4018 rectangle, compare clear lens GSAM4027 or amber GSAM4028. Similar-looking Arcon rectangular lenses are a different system.




Recognize Gustafson oval components
The Gustafson oval family has its own snap-on lens. Check your fixture for AM4032 or AM4033 and compare part GSAM4046 (clear) or GSAM4047 (amber), rather than choosing by appearance alone.



Recognize Command Classic rectangular components
Command Classic 007-50SAC uses the 89100-series cover: clear 89100C or amber 89100A. Do not use either for a Command Omega 007-30 lamp or another manufacturer's rectangle.
