Opel Zafira (1998 to 2005)
The next generation in bulb performance. Xenon bulbs are up to 50% brighter than standard halogen bulbs, but only use 2/3 of the energy, and last longer; they're now very affordable. Fit them with a view to increasing safety as well as reducing driver fatigue - white light is easier to 'digest' than yellow light. They are E-approved and are suitable for use with glass or plastic headlight covers.
