- Provides **warm, yellowish light** (typical of halogens), which some drivers prefer over cooler LEDs.

---

### **Cons**

1. **Lower Efficiency Than LEDs**

- **Only 20% of energy converts to light** (rest is heat), making it **less efficient** than LEDs or HIDs.

- **Generates more heat**, which can **damage plastic lens covers** in some vehicles over time.

2. **Shorter Lifespan Than LEDs**

- While better than standard bulbs, it still **burns out faster** than **LED or HID replacements** (which can last **10,000 hours**).

- Requires **more frequent replacements** compared to modern lighting tech.

3. **UV Radiation & Lens Discoloration**

- Halogen bulbs emit **UV rays**, which can **yellow plastic lenses** over time, reducing clarity.

- May require **additional UV filters** if used in fog lights for long periods.

4. **Not as Bright as HIDs or LEDs**

- While brighter than standard bulbs, it **does not match the intensity** of **HID (xenon) or LED headlights**.

- Some drivers report **glare or discomfort** when driving at night due to **less focused light distribution**.

5. **Potential for Overheating in Poorly Ventilated Enclosures**

- If installed in a **closed or poorly ventilated housing**, the bulb may **overheat**, reducing lifespan or causing **premature failure**.
