Miller 6-Inch Oval Tail Light Mounting Grommet

Secure Mounting for 6-Inch Oval Tail Lights

Ensure your welding trailer remains safe and road-legal with the Miller 274646 Rubber Grommet. Designed specifically for 6-inch oval tail lights, this mounting accessory is a vital component for any Miller running gear or trailer setup. The grommet serves a dual purpose: it securely holds the tail light in place within the trailer frame, and it provides a cushioned suspension system for the light fixture. This cushioning effect is particularly important for welding trailers, which often travel over rough, uneven terrain at construction sites and industrial facilities. Without the shock-absorbing properties of a healthy rubber grommet, rigid mounting could lead to premature bulb failure or cracked housings.

Over time, rubber components can degrade due to UV exposure, ozone, and road salts. A brittle or cracked grommet loses its ability to seal out moisture and hold the light firmly. The Miller 274646 is built from resilient rubber material designed to withstand these harsh environmental conditions, offering a long service life and reliable performance. It creates a tight seal around the perimeter of the light, preventing water ingress that could short out the electrical system. This is especially critical for tail lights, which are positioned low on the trailer and are frequently exposed to road spray and debris.

This product is sold individually and is compatible with standard 6-inch oval lighting configurations used on Miller equipment. The open-back design allows for easy routing of wiring and plugs. To install, simply insert the grommet into the metal panel cutout until the groove seats fully, then lubricate the inside lip slightly and press the light unit into place. Trust in genuine Miller parts to keep your support equipment as reliable as your welding power source.
