Step 9: Wire your circuit to the LEDs on the plate, connect your switches.
Extend two very long wires from your resisted output rail to two tactile switches. These wires should be the distance you need your wires to travel on your bike frame, running from the rear, to your handlebars. Mine were a bit longer than 5 ft long, and then I trimmed as necessary later.
Wire your tactile switches so that the wires are soldered caddy-corner to eachother, then run two more 5 ft wires back to the positive leads on the LED arrays.
