Hi William, LTA does not allow for the installation of aftermarket head lights in Singapore. Vehicles should only be fitted with the default factory fitted head lamps as they meet international safety standards. Using aftermarket head lamps might be hazardous on the road as it might cause unwanted glare. Whatsmore, if the new headlights were not installed properly, there is a chance that it might not work properly, and driving at night without the vehicle's headlights on is an offence. Hope this helps William!
