🛠️ Troubleshooting Common Issues
One side lights not working: Often due to a blown bulb, faulty ground, or loose wiring. Check wiring kits (e.g., Schaudt AD01 relay units) as part of the converter system.
LED replacement flicker: Some users have replaced bulbs with LED types, which can help reduce flicker or failure, though wiring must support them
