SX5-4113010
Enhance night/poor-weather visibility: When it’s dark, rainy, or foggy, the lamp stays on (as part of the “parking light” or “tail light” mode) to outline the right inner edge of the SX5’s rear end. This helps drivers behind you judge your car’s width and position—so they don’t accidentally drift too close to your right side.
Signal braking & turning: It’s linked to the SX5’s brake and turn signal systems. When you hit the brakes, the lamp gets brighter to warn drivers behind you to slow down; when you turn right, it flashes to show your intended direction. This double-up on signals (with the outer tail lamp) makes your moves clearer—even if the outer lamp is blocked by dirt or snow.
Mark the rear body in tight spaces: When parking or reversing in narrow spots (like a garage or tight street), the lamp lights up to show the right inner corner of the rear end. This helps you avoid scraping the bumper against curbs, walls, or other cars—saving you from body damage.
Fits These: All Dongfeng FMC SX5 variants (matches the rear body’s mounting holes, electrical specs, and light function setup—confirm with VIN).
Won’t Fit These:
Other Dongfeng models: Like Dongfeng Lamari T5, AX7, or Forthing T5 EVO—different rear body designs, wiring harnesses, and lamp shapes (can’t attach or work).
Non-Dongfeng vehicles: Even if it looks similar, their rear electrical systems and body sizes differ (no functional fit; may damage the car’s wiring).
SX5 with modified rear body: Aftermarket rear bumpers, trunk spoilers, or custom body kits change the rear mounting space—original lamp can’t fit (leaves gaps or blocks other parts).
Prep: Techs open the SX5’s rear trunk (or remove a small trim panel inside the rear body) to access the lamp’s wiring. They disconnect the old lamp’s terminal and unbolt it from the rear body.
Install new lamp: They line up SX5-4113010 with the rear body’s mounting holes, bolt it tightly (to keep the rubber gasket sealed), then plug in the wiring terminal.
Test: They turn on the parking lights, hit the brakes, and activate the right turn signal—checking that the lamp works for all functions. They also spray a little water around the lamp (to test the seal) and confirm no leaks.
Wipe the lens weekly: Use a soft cloth and mild soap to clean dirt, bug splatters, or road salt off the plastic lens—dirty lenses dim the light (other drivers might miss your signals).
Check the seal every 3 months: Look at the rubber gasket around the lamp—if it’s cracked or loose, have it replaced (prevents water from getting inside and rusting the body).
Replace LEDs (if needed): If the lamp stops working, techs can swap the faulty LEDs with Dongfeng-approved ones—don’t use generic LEDs (they may be too dim or burn out fast).
Inspect after rear impacts: If you bump the rear end (even lightly), check the lamp for cracks or loose wiring—hidden damage can cause the lamp to fail later.
