The majority of motorbikes on the road today are equipped with halogen bulbs for headlighting. With the introduction of the high output halogen range, Philips have once again set a new world standard for halogen bulbs. Modern headlights make increasing use of plastic lenses, as plastic is sensitive to UV radiation. The Philips range of halogen headlighting bulbs are made of UV cut quartz ensuring optimum protection of the headlight materials. What this means is that using Philips bulbs ensures that your lenses won’t go an ‘off yellow’ colour.
