What is the power of the Great Wall M1 headlights in watts?

The Great Wall M1 headlight H15 power is 5W, and the low beam H75 power is 5W. The Great Wall M1 is an SUV with body dimensions of 3645mm in length, 1625mm in width, and 1630mm in height, and a wheelbase of 2296mm. In terms of power, the Great Wall M1 is equipped with a 1.3-liter naturally aspirated engine, which is a four-cylinder engine. In terms of appearance, the most prominent feature of the Great Wall M1's front end is the two round headlights, with a clever layered design inside the headlights. The fog lights are located on the wings of the front bumper, surrounded by two strong curves. The side profile has a distinct personalized effect, with iron-gray angular protective panels adding a lot to the body decoration.
I have a Great Wall M1 at home, and I specifically checked the manual. The original headlights are 55-watt halogen bulbs with an H1 model. This wattage is considered mainstream and is completely sufficient for city driving. If you feel it's not bright enough for mountain roads, I suggest not directly switching to 100-watt high-power bulbs, as they can easily burn out the lamp socket or wiring, making it even more dangerous. I later replaced mine with Osram Night Breaker bulbs, also 55 watts, which significantly improved brightness and are safer. Changing the bulbs is quite simple—just unscrew the dust cover and unplug the connector. It takes about ten minutes to do it yourself. Remember not to touch the bulb glass when changing it, as the oil from your hands can shorten the bulb's lifespan.
Last time I helped my brother repair his Great Wall M1, I specifically measured the headlight power. Both low beam and high beam use 55-watt halogen bulbs, with a starting current around 4.6 amps measured by a multimeter. This power design is quite reasonable - any higher would overload the alternator. I've seen cases where upgrading to 75-watt bulbs melted the wiring harness. The factory lamp sockets typically last 3-4 years, but for frequent night drivers, it's advisable to check for lens yellowing after two years. Yellowed lenses can block half the light output - even upgrading to 100-watt bulbs won't help in this case. The most cost-effective solution is simply polishing the lens.
