The low beam model of the Refine M4 is h7, and the high beam model is h1. When replacing the bulb, it is necessary to turn off the headlight switch in time to allow the bulb to cool down. When installing a new bulb, do not touch it directly with your hands. Relevant information about car headlights is as follows: 1. Car headlights, also known as car front lights or car LED daytime running lights, as the eyes of the car, are not only related to the external image of the owner but also closely connected to safe driving at night or in bad weather conditions. 2. Car headlights include the following 8 types: LED lights, signal lights, halogen lights, width indicator lights, HID xenon lights, left and right turn signals, xenon lights, and fog lights.

I've been driving the Refine M4 for many years. The headlight model of this car is usually H7, used for both high beam and low beam. It's easy to find compatible bulbs with the standard configuration. When replacing them yourself, pay attention to minor variations across different model years. For example, some 2018 models use H1, but it's rare. I recommend checking the vehicle's user manual or calling the 4S store to confirm the model first. Using the wrong bulb type may cause flickering or poor vibration resistance. Regularly checking if the headlights are working is also crucial. If they fail, replacing them promptly can prevent hazards during night driving. I once experienced poor visibility in the rain due to weak lighting. Actually, replacing ordinary halogen bulbs like H7 is simple and inexpensive, but you need to remove the front lamp cover. Beginners should avoid forcing it to prevent damaging parts.

I'm a car novice who just got a Refine M4. After checking online, I found that H7 is the mainstream bulb model for headlights. Owner forums indicate that post-2019 models are basically the same. You can directly search for 'Refine M4 bulb' on JD.com or Taobao—H7 bulbs usually cost less than 30 yuan each. Changing bulbs is quite beginner-friendly; just unscrew the lamp socket cover to operate, but remember to disconnect the power to avoid electric shock. If you're unsure about the model, take a photo of the headlight and ask customer service. A quick reminder: headlight quality affects nighttime safety, especially on mountain roads or highways—don't compromise. My car struggled in foggy conditions due to aging bulbs, but after replacement, visibility improved significantly. Regularly check and clean the lens to prevent dust buildup, as it can halve brightness.

Having worked in the auto industry for years, the Jianghuai Refine M4 mostly uses H7 bulbs for its headlights, suitable for most versions like the business or family models. Before replacing, check the bulb socket. The H7 features a single-filament design with strong versatility, and upgrading to H7-compatible LED or xenon bulbs is easy but requires adjusting the beam height to avoid glare. Specifications may vary by year—for instance, some 2020 high-end models use different specs. It's best to remove the old bulb to check its label or consult a professional mechanic to avoid mistakes. Choosing the right headlight bulb can last up to a year and a half, saving you from frequent replacements and waste. Keep the wiring dry, as rainwater in the socket can corrode connections, leading to flickering or poor contact. Fix issues promptly to prevent more costly repairs later.
