A status indicator LED is wired up to the Nano and installed on the handlebar control switch. One cycles through the various brightness modes on the pushbutton, while the slide switch activates the Strobe function. The handlebar mounted control switch is a generic motorcycle accessory that has two push buttons (horn, headlight) and a slide switch (turn indicators). The hardware is as barebones as possible, consisting of an Arduino Nano, linear regulator, power MOSFET and control switch, with a few discretes thrown in. And since more code wasn’t going to cost him anything extra, he added breathing and strobe modes. He then decided to build a microcontroller based dimmer to offer 33%, 50% and 100% intensities. He chose a commonly available 18 W light bar module containing six 3 W LEDs. from WhiskeyTangoHotel choose the latter route, and built a super simple LED controller for his KLR650 bike. ![]() If you want to add brightness control, you need to either buy a dimmer module, or roll your own. The availability of cheap, high-efficiency LED modules helps add additional lighting to the vehicle without adding a lot of burden on the electrical supply. Most primary lighting on vehicles still relies on tungsten filament lamps which have very poor efficiency. For automobiles, especially motorcycles, auxiliary lighting that augments the headlights can be quite useful, particularly when you need to drive/ride through foggy conditions and poorly lit or unlit roads and dirt tracks.
