Installation Guide

1. Safety First: Ensure the vehicle’s engine is off and the battery disconnected to avoid electrical shock.
2. Access the Headlamp Assembly: Open the hood and locate the rear of the headlamp housing. Remove any protective covers or panels that obstruct access.
3. Remove the Old Bulb: Gently twist the existing bulb counter‑clockwise until it releases from its socket. Carefully pull it out, taking care not to touch the glass element with bare fingers.
4. Insert the New Osram H1: Align the P14.5S base with the socket and insert the bulb clockwise until firmly seated. Avoid applying excessive force.
5. Reassemble: Replace any panels or covers removed during access. Reconnect the battery if it was disconnected.
6. Test the Light: Turn on the vehicle’s headlights to confirm proper operation and beam alignment.

Performance Highlights

• Consistent Brightness: The 70 W power rating ensures a steady, bright illumination that meets or exceeds OEM specifications for the Vario series.
• Longer Lifespan: Advanced halogen technology and high‑quality glass construction reduce flickering and extend operational life compared to standard bulbs.
• Improved Visibility: The warm white color temperature (3,200 K) provides a natural light spectrum that enhances contrast on the road without causing glare for oncoming traffic.
