Diode Dynamics Interior LED Conversion Kit for 2016–2018 Ford Focus RS (Stage 1) replaces interior halogens with 6000K cool white LEDs to refresh cabin appearance and provide a modest bump in brightness. The components are direct-fit molded bulbs with sturdy double terminals and plug-and-play connections, plus two plastic trim removal tools for easier installation. LEDs are tested in-house; rotate a non-lit bulb 180° and reinstall.
