274646 - Miller 6-Inch Oval Tail Light Mounting Grommet

Genuine Miller Replacement Grommet for Trailer Lighting

The Miller 274646 Grommet is a specialized rubber mounting component designed for 6-inch oval tail lights. This part is essential for maintaining the structural integrity and functionality of the lighting systems found on Miller welding trailers and running gear. When transporting heavy welding equipment to and from job sites, the trailer lights are subjected to constant vibration, road shock, and varying weather conditions. This rubber grommet acts as a critical interface between the metal trailer frame and the plastic light housing, absorbing impacts that could otherwise crack the lens or damage the internal filaments of the bulb.

Manufactured to Miller's high standards, this grommet ensures a snug, professional fit that prevents the light from rattling loose during transit. The high-quality rubber compound is formulated to resist drying, cracking, and fading caused by long-term exposure to sunlight and temperature fluctuations. Replacing worn or missing grommets is a simple maintenance task that significantly improves the reliability of your trailer's safety lighting. A compromised grommet can allow moisture to seep behind the light fixture, leading to corrosion of the electrical connections and potential lighting failure. By using this genuine OEM part, you ensure that your equipment remains road-ready and compliant with transportation safety regulations.

Installation is straightforward and requires no special tools. The grommet is designed to press-fit into the standard oval cutout on the trailer chassis, and the light fixture subsequently pushes into the grommet, creating a watertight and dust-tight seal. Whether you are refurbishing an older trailer or replacing a damaged part, the Miller 274646 provides the durability and precise fitment expected from Miller Electric components.
