Semi Lighting Grommet 4 Inch Round Stainless Steel SBC Vacuum advance adjustment toolTruck lights that are not properly installed do not last long. It's considerably easier to spend a few dollars on essential parts and do the job right than it is to repeat the whole job every couple of years. That said, lighting grommets might just be the best investment you can make when installing new lights. They keep road grime, water, salt and more out of your lights and wiring, helping to ensure the longest life from your lights.
