Adding a blind spot monitoring system to existing vehicles is a feasible technical solution. The market offers a variety of modification options compatible with different car models, including aftermarket systems using 77GHz millimeter-wave radar, which have a detection range of up to 70 meters, support non-destructive installation, and do not affect the structural integrity of the original vehicle. When a vehicle is detected entering the blind spot, it will issue a warning via LED lights on the rearview mirror or a combination of sound and light. Installation requires operation by professional technicians, involving steps such as the arrangement of sensors on the rear bumper, wiring harness routing, and modification of rearview mirror indicator lights, taking approximately 2-3 hours. The cost of aftermarket solutions is about 1500-3000 Malaysian Ringgit, while the price of original factory integrated systems may reach 4000-6000 Malaysian Ringgit. Although this system can significantly improve lane-changing safety, especially in complex road conditions such as motorcycle cutting-in, drivers still need to maintain the habit of active observation, and it should be confirmed that the modification complies with local vehicle regulations before installation. Radar-based systems have better stability than camera-based solutions in rainy and foggy weather, but the sensors need to be cleaned regularly to ensure detection accuracy.
