Product Specifications

Designed for 2½" Round Marker & Clearance Lights

The Truck-Lite 10700 is designed to flush-mount compatible 2½-inch round lamps used in commercial vehicle marker and clearance lighting systems.

Its flexible design allows the grommet to be installed in the appropriate panel opening, with the lamp retained securely inside.

Typical applications include:

• Roll-off trailers

• Dump trucks and dump trailers

• Flatbed trailers

• Semi-trailers

• Equipment trailers

• Waste and recycling equipment

• Commercial truck bodies

• Other compatible marker and clearance lighting installations

Fitment depends on lamp diameter, mounting panel thickness, and the installation opening—not simply the type of vehicle.

Wide Groove for Panels Up to ¼" Thick

A key feature of the Truck-Lite 10700 is its wide mounting groove.

Truck-Lite specifies this grommet for panels with a maximum thickness of 0.250 inches (¼ inch).

This makes it useful for installations requiring the wider groove configuration rather than a narrow-groove replacement.

For proper fitment, confirm:

• The mounting panel is no thicker than ¼"

• The opening is the correct diameter

• The lamp measures 2½" in diameter

• The mounting groove can seat properly against the panel

Using an incorrect groove style can prevent the grommet from fitting securely.

Open-Back Design

The 10700 features an open-back construction.

This allows access to the rear of the installed marker light and its electrical connection.

Truck-Lite recommends considering a closed-back grommet for open installations where a splash plate is not used.

The correct mounting arrangement depends on the exposure conditions and the vehicle's original lighting design.

Mounting Dimensions

Truck-Lite publishes the following dimensions:

Important: The 2½-inch measurement refers to the lamp diameter. It is not the diameter of the mounting hole in the trailer panel.

If fabricating a new mounting location, verify the manufacturer's mounting dimensions before cutting.

Truck-Lite 10700 vs. Other 2½" Grommets

Truck-Lite offers several grommet styles for 2½-inch lamps.

These products serve different mounting requirements and should not be assumed interchangeable simply because they accept the same lamp diameter.

Choose Truck-Lite 10700 when your application requires the wide-groove, open-back PVC mounting style.

Replaces Signal-Stat 9119 and 9156

Truck-Lite identifies the 10700 as a replacement for:

• Signal-Stat 9119

• Signal-Stat 9156

These cross-references can help identify the correct replacement when servicing older trailer lighting installations.

Always compare the mounting panel opening, groove size, and lamp diameter before ordering.

Compatible Light Mounting Kit

Truck-Lite also offers the 10401 open-back mounting kit for compatible 2½-inch lights.

That kit combines:

• Truck-Lite 10700 mounting grommet

• Truck-Lite 94902 electrical wiring plug

This listing is for the 10700 grommet only. It does not include the 94902 wiring plug or a lamp.

PC-Rated Lighting Applications

Truck-Lite specifies that this mounting style may be used for applications requiring PC photometric performance when a compatible LED or incandescent PC-rated/combination lamp is mounted at the required 45-degree angle.

The grommet alone does not provide illumination or independently satisfy vehicle lighting requirements.

Always verify the lamp rating, mounting orientation, and applicable regulations.

When Should You Replace a Light Grommet?

Over time, trailer lighting grommets can become damaged from vibration, impact, environmental exposure, or repeated lamp removal.

Common reasons to replace a grommet include:

• Cracked or torn mounting material

• Loose-fitting marker lights

• Damaged mounting groove

• Grommet no longer seated securely in the panel

• Damage during lamp replacement

• Missing mounting components

• Installation of new marker or clearance lights

Inspect the lamp, electrical plug, wiring, and mounting panel when replacing the grommet.

How to Verify the Correct Replacement

1. Confirm the Manufacturer Part Number

Check your original component or equipment documentation for Truck-Lite 10700.

2. Measure the Lamp

Verify that the light is 2½ inches in diameter.

3. Check Panel Thickness

The wide-groove 10700 is designed for panels up to ¼ inch thick.

4. Measure the Mounting Hole

Confirm that the panel opening matches the required installation dimensions.

5. Verify the Back Design

This product has an open back. Determine whether your installation requires a closed-back version.

6. Compare the Original Grommet

Inspect the groove, outside dimensions, and lamp-retaining arrangement before ordering.
