What type of bulb is used in the factory headlights of the 2016 Emgrand GS?

Automobile headlights, also known as automobile front lights or LED daytime running lights, include high beams, low beams, and turn signals. High beams: High beams should only be used when there is no other surrounding light. They are suitable for driving on unlit highways or rural roads at night to expand the field of vision. However, when encountering oncoming traffic, it is necessary to switch to low beams for safety and courtesy. Low beams: Low beams must be turned on when driving in areas without street lighting at night, during dusk when it is relatively dark, or at dawn. They are also required during the day in conditions of heavy fog, snow, or rain that impair visibility. Additionally, low beams should be used on roads with insufficient lighting. Turn signals: The primary purpose of turn signals is to indicate to other drivers and pedestrians when a vehicle is turning, thereby alerting them to be cautious. In some cases, turn signals can also serve as auxiliary lighting in narrow spaces to help drivers observe obstacles on either side.
I've been driving a 2016 Emgrand GS for several years. Its original headlights use halogen H7 bulbs, the 55-watt type, which provide moderate brightness and are quite energy-efficient. The manufacturer chose them mainly for their stability, durability, and affordability—they cost just a few dozen yuan on Taobao. I've replaced them myself a few times, and I’d advise you to be careful when unplugging the connector—don’t use too much force, as the bulb pins can break easily. If you notice dimming or flickering while driving at night, it might be time for a replacement; otherwise, it could pose a safety hazard. If you’re looking to upgrade, LED bulbs are popular now—they’re brighter but require proper heat dissipation. I’ve tried them, and the effect is great, but professional installation is recommended to avoid affecting the electrical system. For maintenance, regularly wipe the lens to prevent dust buildup, which improves visibility in rainy conditions. Though this bulb technology is old, it’s quite reliable.
Last year, I bought a used Emgrand GS 2016 model, which came with factory-installed halogen H7 bulbs, 55-watt output providing even and practical lighting. After checking the car manual, I confirmed that it's cost-effective to replace them myself—easily done with a pair bought online for just 25 yuan. The bulbs provide sufficient illumination at night, though they can get quite hot in summer, so caution is needed. For maintenance, regularly check the electrical connections to ensure they're secure, which extends lifespan and prevents fuse blowouts. If you're into modifications, upgrading to LED bulbs can boost brightness, but always test voltage compatibility first. The bulb design is simple and reliable, ensuring no sudden failures during long drives, making it both economical and slightly more eco-friendly.
I've worked on many Emgrand GS 2016 models, which come standard with H7 halogen bulbs in 55W standard version. This choice balances cost and performance, with a lifespan of about 500 hours. Common issues found during actual maintenance: broken filaments or oxidized bulb sockets—here's a little trick: drive and observe if the headlight beam dims unevenly, if so, replace it immediately to avoid nighttime accidents. It's best to use genuine spare parts purchased from 4S stores for reliability, as they're affordable and easy to replace; also, check the fuses and relays in the circuit to prevent related faults, as wires can leak electricity due to aging over time. Proper maintenance can extend their service life by several years.
