Package Contents
Verify that all items are present in the package:
- 1 x Grote 61221 Clear Square Dome Light (with integrated 3-way switch)
- Mounting Hardware (if included, typically screws)
Setup and Installation
Follow these steps for proper installation:
- Choose Mounting Location: Select a flat, secure surface for mounting the dome light. Ensure there is sufficient space for the light and access for wiring. The light is designed for interior use, typically in vehicle cabins or enclosed spaces.
- Prepare Wiring: The dome light operates on 12 Volts DC. Identify the positive (+) and negative (-) power sources in your vehicle or application. The light includes wires for connection. Typically, red is positive and black is negative/ground. The brown wire is likely for a door switch or constant power, depending on the 3-way switch functionality.
- Wire Connections: Connect the light's wires to the corresponding power sources. Use appropriate wire connectors (e.g., crimp connectors, solder and heat shrink) to ensure secure and insulated connections.
- Mount the Light: Secure the dome light to the chosen surface using appropriate screws. Ensure the light is firmly attached and does not vibrate loose during operation.
- Test Functionality: Once installed, apply power and test the 3-way switch to ensure the light operates correctly in all positions.

Operating Instructions
The Grote 61221 Dome Light features an integrated 3-way switch for versatile operation:
- Position 1 (OFF): The light is completely off, regardless of door status or other inputs.
- Position 2 (DOOR/AUTO): The light will illuminate when a connected door switch is activated (e.g., door opens). This position is typically used for automatic interior lighting.
- Position 3 (ON): The light remains continuously on, regardless of door status.
Move the switch lever to the desired position to control the light.
Maintenance
- Cleaning: Clean the clear lens and housing with a soft, damp cloth. Avoid abrasive cleaners or solvents that may damage the plastic.
- Bulb Replacement: If the incandescent bulb burns out, disconnect power before attempting replacement. Carefully remove the lens cover and replace the bulb with an equivalent 12V incandescent bulb. Ensure the new bulb is securely seated before reattaching the lens cover.
- Wiring Inspection: Periodically inspect wiring connections for signs of wear, corrosion, or looseness. Re-secure or replace any damaged wiring.
