4. Setup and Installation

Follow these steps for proper installation of your reversing light:

Choose Mounting Location: Select a suitable flat surface at the rear of the vehicle for surface mounting. Ensure it complies with local regulations for reversing light placement.
Prepare Mounting Surface: Clean the chosen area thoroughly. Mark the drilling points for the mounting screws using the light unit as a template.
Drill Holes: Carefully drill pilot holes for the mounting screws and a larger hole for the wiring to pass through, if necessary. Deburr any sharp edges.
Install Bulb: Open the light unit (if required) and insert a compatible C21W incandescent bulb (not supplied). Ensure it is seated correctly.
Wire Connection: Connect the light's wiring to the vehicle's reversing light circuit. Typically, this involves connecting the positive wire of the light to the positive wire of the reversing light circuit and the negative wire to a suitable ground point on the vehicle chassis. Ensure connections are secure and waterproof.
Mount the Light: Secure the light unit to the vehicle using the provided mounting hardware. Do not overtighten screws.
Test Functionality: Reconnect the vehicle battery. Engage reverse gear (with the engine off and parking brake on, or vehicle safely supported) and verify that the reversing light illuminates correctly.

5. Operating Instructions

The HELLA 2ZR 001 421-101 Reversing Light operates automatically. When properly installed and wired, it will illuminate when the vehicle's transmission is shifted into reverse gear and the ignition is on. It will turn off when reverse gear is disengaged.

6. Maintenance

Cleaning: Periodically clean the lens of the reversing light with a soft cloth and mild soap and water to ensure maximum light output. Avoid abrasive cleaners.
Bulb Replacement: If the light stops working, the C21W bulb may need replacement. Disconnect the vehicle battery, carefully open the light unit, remove the old bulb, and insert a new C21W bulb. Ensure the new bulb is correctly seated before reassembling the unit.
Inspection: Regularly check the mounting and wiring for any signs of damage, corrosion, or looseness.
