I am thinking of purchasing the Kuryakyn Halogen Universal Silver Bullet Kits and mount on my engine guards. Has anyone done a similar install? How did it go? Any warnings? Is it necessary to install the Universal Wiring & Relay Kit for this installation? These lights are 35 watts which are the same as Kuryakyn Light Bar, which requires (strongly suggested by manufacture) the Universal Wiring & Relay Kit. :?
