Functional Overview of Ford Scorpio 95+ Headlamp System

A printable PDF version of this page is available HERE

Introduction
The 95+ Scorpio, utilises standard automotive headlamp technology, albeit in a revolutionary polyelipsoid design.  H1 Halogen 55W lamps are used for both the Dipped Beam and Main Beam illumination and standard filament lamps are used for the side lights.

The Head lighting system contains 6 lamps, 3 per side.

1. Dipped Beam
2. Main Beam (& Headlight Flasher)
3. Side lamps/Parking Lights/Dim dip Running Lights (Pre facelift models only).

Changing Halogen Lamps
When fitting replacement or upgraded headlamp bulbs, its important that no grease from the fingers is allowed to contaminate the glass envelope of the bulb. Grease will cause hot spots, resulting in black marks and premature failure of bulbs due to overheating. If you do happen to touch the glass envelope, use methalated spirits or IPA cleaning fluid to fully remove any grease residue.
