  【Product Introduction】

Halogen lamp, also known as tungsten-halogen bulb, is a type of incandescent light bulb. The principle involves injecting halogen gases such as iodine or bromine into the bulb. At high temperatures, the sublimated tungsten filament reacts chemically with the halogens. The sublimated tungsten re-crystallizes on the filament, creating a balanced cycle that prevents premature breakage of the filament. Therefore, halogen lamps have a longer lifespan than incandescent bulbs.

【Product Features】
1. Halogen bulbs (hard glass, quartz glass) can also operate at higher temperatures than conventional incandescent bulbs, and they offer higher brightness and efficiency. They have many advantages: simplicity, low cost, easy adjustment and control of brightness, good color rendering, etc.

2By utilizing advanced halogen technology, it effectively enhances the light performance and service life of the product, providing drivers with an excellent lighting range and ensuring safer driving conditions. The precise filament positioning technology ensures optimal light distribution, minimizing glare from other vehicles and offering drivers excellent lighting comfort.

【Precautions】
1. When installing halogen bulbs, turn off the power supply and use a plastic cover to protect the bulb glass shell. Do not touch it with your hands; if accidental contact occurs, wipe it clean with alcohol.
2. Halogen bulbs are made of high-temperature resistant hard glass (quartz glass). If they come into contact with hands or oil, the hard glass will lose its luster, turn white and cloudy, reduce brightness, shorten lifespan, and even cause the glass shell to break.
3. When a halogen bulb is lit, the temperature at the sealing area must not exceed 350 degrees Celsius; otherwise, the lifespan of the halogen bulb will be reduced. Therefore, ventilation and heat dissipation for halogen lighting must be adequate.
4. When the halide bulb is lit, avoid direct cold air blowing towards the bulb.
5. When the halogen bulb is being lit, avoid any impact or vibration.
6. When a halogen bulb is being lit or just turned off, it is absolutely not safe to touch due to the high temperature of the bulb.

【Installation Instructions】
1. Engine off state of the car when it is cold
2. Open the engine cover and remove the waterproof plastic cover behind the bulb.
3. Unplug the light bulb from the power socket
4. Remove the bulb from the reflector cover; it is usually held in place by a steel spring clip (some have a plastic base).
5. Remove the new Guangtai bulb. Hold the bottom of the bulb; be careful not to touch the glass part with your hands, to prevent stains or damage to the bulb.
6. Fix the new bulb inside the reflector cover
7. Plug in the bulb power supply and cover the waterproof plastic cover again.
8. Cover the engine cover
