Illuminate the rear cabin for daily use: When  passengers need to find a phone, bag, or small item (especially at night or in dark garages), they can flip the lamp’s manual switch to turn it on. The light covers the entire rear seat area evenly—bright enough to see details, but soft enough to avoid dazzling anyone sitting in the back. It also works as a “reading light” for passengers who want to read books or documents during trips.

Signal safety when doors are open: Most Haima S7 variants link this rear roof lamp to the door sensors. When any rear door (or even front doors, depending on settings) is opened, the lamp automatically turns on. This warns nearby pedestrians, cyclists, or drivers that the S7’s doors are open—preventing accidental collisions (e.g., a passing bike hitting an open rear door) and making the vehicle more visible in low-light environments.

Fits These: All Haima S7 variants (matches the roof cutout size, interior wiring harness, and door sensor system—confirm with VIN).

Won’t Fit These:

Other Haima models: Like Haima S5, 7X, or M3—different roof sizes, interior wiring layouts, and door sensor protocols (can’t install or work with auto-on).

Non-Haima vehicles: Even if similar in look, roof mounting points and electrical specs differ (no functional fit; may damage the vehicle’s wiring).

S7 with modified roof interiors: Aftermarket sunroofs, roof racks, or custom headliners that change the original roof cutout—original lamp can’t fit (leaves gaps or blocks other parts).

Wipe the lens weekly: Use a soft, dry cloth to clean dust or fingerprints off the lamp’s lens—dirty lenses make the light dim (hard to see in the rear).

Check auto-on function monthly: Open/close all doors to make sure the lamp turns on/off automatically—if it doesn’t, have techs check the door sensor (not the lamp itself, usually a small fix).

Replace the light source if needed: If the lamp goes dark, techs can swap the bulb/LED (use Haima-approved parts—wrong bulbs may overheat and damage the housing).

Fix loose mounting clips: If the lamp rattles, have techs replace the worn clips—loose lamps can scratch the roof liner over time.
