High Temperature Resistant H4 LED Bulb for Car/Motorcycle Headlights (AC 12V / DC 12–40V); Color Temperature: 6000–6500K.

This LED bulb has built-in decoding functions, making it compatible with 95% of vehicle models on the market. During installation, please connect the bulb and test it before reassembling the headlight housing; start the engine to check for issues such as flickering, dashboard warning lights, or failure to illuminate. If none of these occur, the decoding is successful, and the bulb is ready for use. If problems arise, you can choose to purchase a separate decoder. This is a new, high-quality H4/HS1 12V DC LED bulb designed specifically for classic vehicles and compatible with 12V DC electrical systems (supports both positive and negative ground).\nFor vintage vehicles, LED bulbs not only offer superior illumination but also the advantage of low power consumption – a crucial benefit for older cars with limited alternator output.\nThis headlight bulb supports both low and high beams, with a specific diode arrangement to switch between them. The light pattern is precisely engineered to avoid dazzling oncoming traffic!\nSpecifications:\nActual power consumption: 40W; Color temperature: 6500K; Brightness significantly exceeds that of standard 60/55W bulbs; Connector type: H4/HS1. Highly recommended!\nElectromechanical system problems can often be challenging for my customers. I am happy to assist with advice on component selection – such as LED bulbs and voltage regulators – for popular classic models, and I also welcome inquiries regarding rare vehicles.\nI advise against purchasing complete accessory kits on your own.\nLow Beam / High Beam
