Lights coming from those shiny ebay surface mount 5050 LED strips taped under the red plastics. Connector is a 4 pin aviation-styled thingy, socket screwed in the bottom of the box, plug routed from the seat and under the rack. Topbox is on 24/7 so I don't need a quick-release connector (also most of those are only 2 pins... I need 4 for these lights)
Currently it is taken apart because I lost one of the red plastics after an accident. Parts arrived, just need time to reassemble the whole thing.
Meanwhile I designed a little controller which will enable all the lights to be "half brightness on" while driving, "full brightness" when braking, side lights flashing with the blinkers. Also includes a brake light flasher function and parking lights. Details later when I get out to the garage.
