ORACLE Lighting illuminated LED wheel rings are an easy and effective way to light up the wheels on your car or truck! This head-turning lighting product consists of a set of (4) LED illuminated aluminum rings which install around the brake rotor and attaches to the brake dust shield. These can also be mounted to older vehicles with drum brakes. The effect is a large ring of light which accents custom wheels and stands out at events. Oversized 16.5" diameter is the largest on the market and fits oversized brakes. This kit now features a TRUE white 6000K from separate white LEDs for a TRUE WHITE output for a Crisp & Clean white light.

Now featuring Dual-Control allowing the user to use both the free Bluetooth Smartphone App control PLUS the included Wireless Remote Control. Installation is easy with waterproof Plug & Play Connectors that easily connect the individual rings to the central control box. Battery connection leads include ring terminals and in-line fuse for simplified wiring installation. There is also a pre-wired On/Off switch that can be used to manually turn the system on and off for maximum control. Additional upgrades to our LED wheel lights include thicker aluminum rings black powder-coat anti-corrosive finish waterproof connectors and pre-installed brackets. Installation tip: For extra security of the screws holding in the brackets on wheel rings first confirm that the wheel rings' brackets are in the correct mounting location. Then apply an appropriate amount of Loctite to these screws to ensure a firm hold. If your vehicle is equipped with drum brakes or does not have a brake dust shield you will need to perform additional fabrication of brackets to fit properly. Please note these rings are not intended for use while driving.
