The Blind Spot Monitoring (BSM) system can indeed be retrofitted to vehicles to enhance safety. The market currently offers various solutions, including standalone kits utilizing 77GHz millimeter-wave radar technology, priced from approximately 1,500 to 6,000 Malaysian Ringgit, depending on the system type and installation complexity. These systems typically feature a 70-meter detection range, alerting drivers to vehicles in blind spots through rearview mirror indicators and audio-visual warnings, while supporting non-invasive installation to maintain the original vehicle structure. For instance, the dedicated BSM retrofit kit for models like the Toyota Land Cruiser Prado employs a dual-sensor design while preserving the OEM mirror appearance, with installation requiring approximately 2.5 hours. Notably, new vehicles such as the 2024 Isuzu D-MAX now come standard with an ADAS system incorporating blind spot detection, utilizing stereoscopic camera technology to achieve a 150-meter detection range. When selecting retrofit options, certified radar-based systems are recommended as they demonstrate superior stability in rainy or foggy conditions compared to vision-only solutions. However, precise sensor positioning (typically on both sides of the rear bumper) and regular maintenance are essential. It must be emphasized that this system serves as an assistive feature, and drivers must always verify conditions using their rearview mirrors before making maneuvers.
