H4 LED bulb set RS+ Series 50W slim CANbus universal — No name
The H4 LED bulb set RS+ Series 50W slim CANbus universal is a pair of automotive headlight bulbs designed as a direct replacement for standard H4 halogen lamps. These LED units deliver the equivalent function of an H4 (dual filament) system in a compact slim housing that reduces heat build-up and power consumption while preserving high beam/low beam functionality. The CANbus compatibility helps avoid error messages on vehicles with monitoring circuits and supports plug-and-play installation in vehicles that accept universal H4 LED replacements.
The slim RS+ Series design provides efficient thermal management and a smaller footprint in the headlamp housing compared with bulkier LED modules. Total rated power of 50W ensures brighter illumination than many OEM halogen bulbs while keeping electrical load lower than some older aftermarket LEDs. CANbus compatibility reduces the risk of dashboard warnings and false bulb failure indications on modern vehicles. The construction aims for stable light output and consistent beam pattern where the reflector or projector is compatible with H4 LED elements.
Switch off the vehicle electrical system and allow the original halogen bulbs and headlamp area to cool before beginning installation. Remove the headlamp cover and disconnect the factory H4 bulb connector, then install the RS+ Series LED unit into the H4 socket, ensuring correct orientation for beam pattern. Reconnect any factory plugs and secure headlamp covers. After installation, test both low and high beam functions and verify headlight aiming and beam cutoff to ensure compliance with local regulations.
For optimal performance, use these LED bulbs in headlamp reflectors or projectors that are compatible with LED light sources and check beam alignment after installation. If the vehicle still shows a dashboard error, an additional load resistor or dedicated CANbus adapter may be required depending on the vehicle's electrical system. Do not operate damaged or improperly mounted bulbs; consult a qualified technician if unsure about fitment or electrical compatibility.
