This lighting mod is intended to be an enhancement for the incredible "Robot Eye" start button designed, developed, handcrafted, and sold by Bill at SuperSkillShot.com:

By default, your original GNR start button lamp is wired to "blink" on and off, which doesn't suit the cyborg eyeball motif very well, so let's make it pulse menacingly, instead!
This mod makes use of an unused connector with continuous 12V power and adds an inline controller that enables you to control how you'd like your "Robot Eye" lamp to behave. By default, I'll have the controller set to a subtle random pulsing mode, but the controller has hundreds of possible settings from a simple 'steady on' lamp at a selectable brightness to flashing at selectable speeds.
Once you have the playfield up, installation takes less than 30 seconds!
Bill's mod looks best with this red-colored LED, if your button didn't already ship with it (I think all of his more recent buttons do include this): https://www.superbrightleds.com/moreinfo/miniature-and-subminiature-bulbs/194-led-bulb-1-led-miniature-wedge-retrofit-car/197/848/
