2. Safety Information
Always observe the following safety precautions when handling and installing automotive bulbs:
- Ensure the vehicle's ignition is off and the headlights are switched off before beginning installation.
- Allow bulbs to cool down completely before handling if they have been recently in use. Halogen bulbs can become extremely hot.
- Wear protective gloves and eye protection during installation.
- Avoid touching the glass part of the bulb with bare hands. Oils from your skin can create hot spots, leading to premature bulb failure. If touched, clean with rubbing alcohol.
- Keep bulbs out of reach of children.
- Dispose of old bulbs responsibly according to local regulations.
- Verify that the replacement bulb's voltage (24V) and wattage (70W) match your vehicle's specifications to prevent damage to the electrical system.
