Axel Joost Elektronik Parts & Accessories

Axel Joost Elektronik build compact, programmable control modules for motorcycle wiring — the elektronikbox units combine horn, turn signals, headlight, and starter control into a single module, eliminating bulky relays and simplifying wiring looms on custom Harley builds. Founded in Germany in 1999.

The B-Box is one of the smallest all-in-one solutions available. The Multi Flasher Plus adds auto-cancelling indicators and hazard function. If you're building something clean and want the electrics to match, Axel Joost is worth knowing about.
