Prototypes are nearly complete and the LED's should be available for purchase in approximately 4-6 weeks. Pricing will be annouced at time of release. These are designed to go behind the 86-92 IROC / Z/28 lenses. I have linked a you tube video to show sequencing. You can contact us or Spaghetti Engineering for further information.
