Operating Instructions

The Bosch H7 Plus 90 headlight bulb operates as a direct replacement for standard H7 halogen bulbs. Its operation is controlled by your vehicle's existing lighting system.

• Activation: Turn on your vehicle's headlights using the standard controls (e.g., headlight switch on the dashboard or steering column).
• Beam Selection: Switch between low beam and high beam as required by driving conditions and traffic laws. The Plus 90 bulb enhances both.
• Optimal Performance: For best performance, ensure your vehicle's electrical system is in good working order. Consistent voltage supply is crucial for bulb longevity and brightness.

Maintenance

Halogen bulbs generally require minimal maintenance. However, following these guidelines can help ensure their longevity and optimal performance.

• Regular Inspection: Periodically check your headlights for proper function. Replace bulbs in pairs if possible, as bulbs from the same batch tend to fail around the same time.
• Clean Headlight Lenses: Keep your vehicle's headlight lenses clean from dirt, grime, and oxidation. A clean lens allows maximum light output.
• Avoid Contamination: As mentioned in safety, avoid touching the glass of the bulb. If you need to handle it, use clean gloves or a lint-free cloth.
• Voltage Stability: Ensure your vehicle's electrical system is stable. Voltage spikes or drops can shorten bulb life.
