Troubleshooting
Light not working
Check all bulb connections are secure. Verify the 5-pin and 4-pin plugs are fully inserted. Test bulbs individually. Ensure the trailer's earth connection is sound.
Indicator flashing too fast or not at all
Ensure the correct wattage bulbs are installed. Check for loose connections in the indicator circuit. If using LEDs (not supplied with this unit), a load resistor may be needed.
Brake light remains on
Verify the 5w/21w dual-contact bulb is correctly seated and wired. Check for shorts in the brake light wiring.
Water ingress into the light unit
Ensure the lens seal is intact and the unit is securely mounted. Check for cracks in the casing. If leaking, the unit may need replacement.
