Review on 🔘 RAM Mounts Ball Adapter with M10 X 1.25 Threaded Post RAM-B-349U - B Size 1" Ball by Jignesh Shaffer

I installed them on my truck as light mounts. They have been stable for 3 months. The lights weigh about 2 pounds and are rated at 5 so they're perfect for the job. Even on the highway there is absolutely no vibration. Riding over bumps results in little bounce and they don't lose alignment at all.
