274645 - Miller 2-Inch Round Rubber Light Grommet

Keep Your Rig Road-Ready with the Miller 274645

When you are hauling your welder to a job site, the last thing you need is to be pulled over for a missing or rattling tail light. The Miller 274645 Grommet is the direct replacement part you need to keep your 2-inch round tail lights secure on your Miller trailer or running gear. Over time, the rubber on your trailer lights can dry out, crack, or shrink due to sun exposure and harsh weather. When this happens, your lights can become loose, letting in water that corrodes the wiring or, worse, popping out completely while you are driving down the highway. This simple, affordable fix helps you protect your investment and maintain a professional appearance for your mobile welding business.

Designed specifically for Miller equipment, this rubber grommet offers a perfect fit that you might not get with generic hardware store parts. It acts as a shock absorber for your lights. Welding trailers take a beating—bouncing over curbs, navigating gravel driveways, and enduring the vibration of the road. This rubber cushion helps isolate the light fixture from that metal-on-plastic impact, which helps your bulbs last longer and keeps the housing from cracking. It is a small part that plays a big role in the safety and reliability of your setup.

Installation is quick and requires no special tools. Simply pop out the old, worn grommet, clean the opening on your trailer frame, and seat the new Miller 274645 grommet into the hole. Then, push your 2-inch round light back into place. The fresh rubber will grip the light tightly, creating a seal that keeps dirt and moisture out. Whether you are refurbishing an older running gear setup or just doing routine maintenance on your rig, sticking with genuine Miller parts ensures everything fits right the first time, getting you back to work faster.
