A phone app uses a Bluetooth OBD adapter to play headlight effects on compatible Mercedes-Benz vehicles.

Landing page captured for the 2026-09-07 issue.

Field notes

MercLight describes a diagnostic-command workflow rather than a hardware modification: the phone connects through a Bluetooth OBD-II adapter, reads the vehicle identification number, and addresses the lighting modules temporarily. The interface is organized around effect tiles, saved playlists, combos, and an unlock-triggered mode. The page names KONNWEI and vLinker BLE adapters, offers five free effects, and says the remaining 25 require one purchase. A demo vehicle is provided for exploring the screens without a connected car.
