4-Inch Round Black ABS Flange-Mount Light Bezel

The 4-Inch Round Black ABS Flange-Mount Light Bezel provides a clean mounting solution for compatible 4-inch round vehicle and trailer lights.

Constructed from black ABS plastic, the bezel surrounds the lamp and provides a flange-style mounting surface, making it useful for replacement installations, custom lighting projects, and applications where a traditional rubber grommet appearance isn't desired.

The 4-inch round format is widely used for stop/turn/tail, backup, park/turn, auxiliary, and other truck and trailer lights, making flange bezels a common accessory within commercial vehicle lighting systems.

Comparable black plastic 4-inch flange bezels allow the lamp to snap into the bezel while the bezel provides the mounting points for installation. Some designs use an open back to maintain access to the lamp's wiring.

Black ABS Construction

The bezel is manufactured from black ABS, providing a practical mounting and trim solution without the weight of a metal flange.

The black finish also creates a clean appearance that works particularly well with black lamp housings, bumpers, body panels, utility bodies, and equipment installations.

Designed for 4-Inch Round Lights

This bezel is intended for compatible 4-inch round lights, one of the most common lamp formats used throughout truck and trailer lighting.

Comparable 4-inch flange bezels are specifically designed to secure round sealed lamps and provide a finished flange-mounted appearance.

Flange-Mount Configuration

The flange design provides an alternative to a standard rubber grommet installation.

With compatible flange systems, the light is retained by the bezel/flange, while the bezel itself is secured to the vehicle or mounting surface.

For example, a comparable Optronics 4-inch black plastic flange allows the light to snap directly into the bracket and explicitly requires no separate grommet.

Mounting Accessory Only

This product is the mounting bezel only.

Light is not included.

Customers should select the appropriate compatible 4-inch round lamp separately.

• Warning lights
• Other 4-inch round vehicle lights

Important Fitment Note

Before ordering, verify:

• 4-inch round light format
• Light's actual outside diameter
• Bezel's inside opening
• Flange mounting dimensions
• Mounting-hole pattern and spacing
• Available installation depth
• Clearance for the lamp and wiring
• Compatibility between the specific lamp and bezel

“4-inch round” is a nominal lighting category and does not guarantee that every 4-inch lamp fits every 4-inch bezel. For example, one comparable flange has a 4-9/16-inch inner diameter and is designed around specific 4-inch lamp dimensions.

The exact overall bezel diameter, inside diameter, mounting-hole count, mounting-hole spacing, mounting hardware, and compatible light series should be verified for this specific product rather than assumed from similar 4-inch bezels.
