The Grayston Competition Lamp Steady Bars are designed to stabilise auxiliary drive and spot lamps by reducing vibration. Using threaded support bars with ball and socket joint ends, they limit movement under load, helping you maintain a consistent beam pattern and reduce vibration-related lamp failure.The key features of these steady bars include:Threaded Steel Support Bars: Manufactured from rigid threaded steel bar, these supports create a direct mechanical link between the lamp housing and the chassis which reduces oscillation from road shock and engine vibration, helping you maintain beam alignment and improving long-term reliability of your lighting setup.Removable Ball and Socket Joint Ends: Supplied with four articulating ball and socket joints featuring threaded mounting studs, these ends allow angular adjustment during installation so you can align the bar correctly to the lamp and mounting point, resulting in secure fitment and controlled movement under load.210mm Maximum Mo
