A stranger off eBay got me pulled over, from across the world.
I have a 1983 Kawasaki CSR 305 that has a hint of a cafe racer. For the look, I replaced the stock brake and turn lights with an LED brake/turn light combo from eBay. It was manufactured overseas, very cheaply.
typical cheap brake/turn light
Something failed and the lights went out…at night…while riding. This upset the local authorities.
I wasn’t able to find a good quality brake/turn light combo that looked good for under $100, so I decided to build my own.
simple current control for running, plate, brake, left, and right turn lights
pcb layout - designed in circuitmaker (extra traces for heat dissipation)
I removed the board from my broken eBay brake light and designed a board that would fit into the same enclosure. The PCB is from OSH Park.
I bought 1000mcd 120° red and amber LEDs. They are astoundingly bright.
