Car headlights lampshades made of different materials have their own advantages and disadvantages. The following are their characteristics:

1. Glass lampshade:

Advantages:

-High light transmittance: providing clear light transmission effect.

-Heat resistance: able to withstand high temperature and not easily deformed.

-Scratch resistance: It has good scratch resistance and wear resistance.

Disadvantages:

-Heavy weight: relatively heavy, increasing the load of the car.

-Fragility: It is easily broken by external force.

-Higher cost: The manufacturing cost is relatively high.

2. Plastic lampshade:

Advantages:

-Lightweight: Lightweight, reducing the load on the car.

-Impact resistance: It has good impact resistance.

Good formability: easy to process into various shapes.

Disadvantages:

-easy to age: easy to age under the influence of ultraviolet rays and chemicals.

-Discoloration: Discoloration may occur after long-term use.

-Poor light transmittance: Compared with glass and resin, the light transmittance is slightly inferior.

3. Resin lampshade:

Advantages:

-Good optical performance: providing clear and uniform light transmission effect.

-Strong weather resistance: it has good weather resistance and ultraviolet resistance.

-Anti-aging: not easily affected by external environment.

Disadvantages:

-Higher cost: Compared with plastic lampshades, the manufacturing cost is higher.

-Possible discoloration: slight discoloration may occur after long-term use.

4. Silica gel:

Advantages:

-High temperature resistance: it can withstand high temperature and is not easy to deform.

-Good weather resistance: It has good weather resistance.

-Strong sealing: it can effectively prevent water vapor and dust from entering the interior of the lamp.

Disadvantages:

-Poor light transmission: not suitable for lampshade materials, usually used for sealing rings and waterproof covers.

To sum up, different materials of car headlights lampshades have their own advantages and disadvantages, and consumers should comprehensively consider the demand and budget when choosing them. Glass lampshade is light but fragile, plastic lampshade is light but easy to age, resin lampshade has good optical performance but high cost, and silica gel is suitable for sealing but poor light transmittance.
