How does the retaining clip hold the bulb in place on a 56 reg fiesta?

The retaining clip on a 56-reg Ford Fiesta secures the headlight bulb by locking it into the housing. When the bulb is inserted, the clip is pushed down or slid into position, creating tension that holds the bulb firmly in place, preventing it from moving or becoming dislodged. This design ensures a proper electrical connection and maintains the bulb's alignment for optimal lighting performance. To replace the bulb, the clip can be released, allowing for easy removal and installation.
