【Product Introduction】
Halogen lamp, also known as tungsten halide lamp, is a type of incandescent lamp. The principle is to inject iodine or bromine and other halogen gases into the bulb. Under high temperature, the sublimated tungsten wire reacts chemically with the halogen. The sublimated tungsten will re-solidify on the tungsten wire, forming a balanced cycle, avoiding premature breakage of the tungsten wire. Therefore, halogen lamps are longer-lasting than incandescent lamps.

【Product Features】
1、Halogen lamps (hard glass, quartz glass) can operate at higher temperatures than general incandescent lamps, and they have higher brightness and efficiency. They have many advantages: simplicity, low cost, easy brightness adjustment and control, good color rendering, and so on.

2. Adopting advanced halogen technology, it effectively improves the product's light efficiency and service life, providing drivers with excellent illumination range and ensuring road safety. The precise filament positioning technology ensures good light distribution, reducing the blinding effect on the other vehicle to a minimum, providing drivers with excellent lighting comfort.

【Product Introduction】
H4: Headlamp with both low and high beam in one bulb, with three rear contact pins.

H1: Separate headlamp bulbs for low beam and high beam, typically used for high beam more, with one plug at the back.

H3: Separate headlamp bulbs for high beams, commonly used for fog lights, with a wire attached to the back.

H7: Separate headlamp bulbs for low and high beams, usually used for low beams more, with two pins at the back.

【注意事项】
1. When installing halogen bulbs, please turn off the power and use plastic covers to protect the glass shell of the bulb. Clean the glass shell, but do not touch it with your hands. If you accidentally touch it, please wipe it clean with alcohol.
2. Halogen lamps are made of hard, heat-resistant glass (quartz glass), and if they come into contact with hands or oil, they will lose their luster, turn opalescent, reduce brightness, shorten their lifespan, and even cause the glass shell to break.
3. When halogen lamps are lit, the temperature at the sealing point must not exceed 350 degrees, or the life of the halogen lamp will be shortened. Therefore, the ventilation and heat dissipation of halogen lamps must be good.
4. When lighting halogen lamps, avoid direct cold air blowing towards the bulb.
5. Avoid impact or vibration when lighting halogen bulbs.
6. When a halogen bulb is on or just turned off, as the bulb is still very hot, it is absolutely forbidden to touch it with your hands.

Installation Instructions
1. Car in idle cold state
2. Open the hood of the engine, remove the waterproof plastic cover behind the bulb.
3. Remove the bulb from the power outlet.
4. Remove the bulb from the reflector cover; it is usually held in place by a spring clip (for some models with a plastic base).
5. Remove the new Guangtai bulb. Hold the bottom of the bulb, and do not touch the glass shell to prevent stains or damage to the bulb.
6. Fix the new bulb into the reflector cover.
7. Plug in the bulb's power supply and re-cover with the waterproof plastic lid.
8、Close the hood
