Is the LED headlight modification for Geely Emgrand GS bright?

[McRose]

Modifying the headlights of the Geely Emgrand GS to LED is brighter than the original headlights. LED headlights refer to car lights that use LEDs (Light Emitting Diodes) as the light source. Because LEDs have the characteristics of high brightness, rich color variety, low power consumption, and long lifespan, they are widely used in the automotive field. LED license plate lights are installed above or on both sides of the rear license plate of the car to illuminate the rear license plate, with a power generally ranging from 1-2W, ensuring that pedestrians can clearly see the text and numbers on the license plate from 20 meters behind the vehicle. LED reverse lights are installed at the rear of the car and automatically light up when the transmission is in reverse gear, illuminating the rear side of the car while warning pedestrians and vehicles behind to pay attention to safety. The power is generally 2-5W, with white light. Brake lights, commonly known as 'LED brake lights,' are installed at the rear of the car. They emit strong red light when the brake pedal is pressed to indicate braking. The power is 2-5W, with red light, and the lens display area is larger than that of the rear position lights. To avoid the danger of large vehicles colliding with sedans from behind, a high-mounted brake light (LED light strip) composed of rows of LEDs can be installed inside the rear window of the sedan.

My previous Emgrand GS had its lights upgraded to LEDs, and the brightness improvement was really noticeable to the naked eye, especially when driving on highways at night—the white light illuminated much farther. However, it's important to choose the right bulb socket model. A friend of mine went for a cheap off-brand option, and due to poor heat dissipation, the reflector bowl ended up turning yellow. Also, remember to find a shop with a decoder for installation. The car's ECU is quite sensitive, and improper connections can trigger fault codes.

After upgrading to LED lights, the penetration in rainy conditions may be compromised. The original halogen bulbs' 3000K yellow light is actually more practical in foggy weather. I compared the lighting data of the same car model before and after the modification: the low beam lumen value increased by 120%, but the color temperature reached 6000K, resulting in a 15% reduction in visibility distance during rainy and foggy conditions. It is recommended to retain the front fog lights for those who frequently drive on mountain roads.

As a ten-year auto mechanic, I want to remind you of three points: First, check if the headlight assembly comes with a lens. Directly replacing LEDs in the Emgrand GS's reflector bowl will cause glare and scattered light. Second, modifying the lights might cause issues during annual inspections. Third, altering the wiring for light modifications will void the warranty. Last week, I just repaired a car that caught fire due to circuit overload. The original wiring harness was designed for 55W halogen bulbs, and suddenly upgrading to 100W requires adding a relay.

The modification indeed made it much brighter, but I've encountered an embarrassing situation – the LED lights actually frosted over during winter startup! The mechanic said it was caused by the cooling fan drawing in moisture. Now I always wait for the engine to warm up before turning on the lights. Additionally, my neighbors kept complaining that my headlights were too dazzling. It took me five attempts to manually adjust the beam angle before it met the standard. I'd recommend going directly to a professional shop for adjustment.

Let me break it down for you: Original halogen bulbs cost 55 yuan/pair and last two years, while brand LED lights cost 300 yuan and last five years, but the modification fee is 500 yuan. The 4S store quoted 2800 yuan for the original high-end LED assembly. In the end, I chose the used parts option—I spent 800 yuan on an original LED headlight assembly from a rear-ended car and had a technician install it. The result looks exactly like the top-tier version, and it passes the annual inspection with no issues.
