Most replacement halogen bulbs are available in either a twin pack ... Each bulb is said to be made from the highest quality quartz glass and alloy filaments, designed and constructed for long ...

That sounds impressive until you read the fine print: "compared with worn standard halogen" bulbs. Still, such claims are making premium-priced halogen bulbs an alluring choice for drivers.

While you shouldn't touch halogen bulbs with your bare hands (the oils from your fingers will make hotspots on the quartz glass), it should be fine to handle both HID and LED headlights.
