Vehicles not originally equipped with fog lights by the manufacturer can legally have them retrofitted, provided that all regulatory requirements and technical standards are strictly complied with. First, it must be ensured that the retrofitted fog lights utilize yellow light sources without altering the vehicle's original structural appearance or performance parameters. Upon approval, the installation must be performed by a certified maintenance facility. Critical inspections include verifying whether the vehicle has pre-existing wiring harness interfaces. If electrical modifications are necessary, only MS-standard compliant fog light assemblies may be used, with proper wiring practices to prevent short-circuit risks. Post-modification, the vehicle registration details must be updated; failure to do so may result in fines ranging from 200 to 500 ringgit or annual inspection rejection. During routine operation, note that fog lights should only be activated during low-visibility conditions to avoid glare interference with other vehicles, while regular inspections of bulb functionality and wiring integrity are required. It is strongly advised to opt for manufacturer-approved solutions or certified aftermarket components to ensure full compliance with UNECE R48 lighting regulations.
