To upgrade the lighting system on a VW T25, consider replacing the standard bulbs with halogen or LED bulbs for improved brightness and energy efficiency. Installing headlamp relays can enhance the performance of the headlights by ensuring a direct power supply from the battery. Upgrading to modern headlight assemblies, such as H4 or square headlamps, can also significantly improve visibility. Ensure all connections are secure and consider adding fog lights for better visibility in adverse weather conditions.
