Built to last
Maximum vibration resistance
The Philips MasterDuty headlight bulbs are designed for maximum vibration resistance and excellent lifetime. They provide more light. Philips MasterDuty is the right choice for drivers seeking toughness that lasts.

Durable lights with increased resistance to vibration
Philips MasterDuty features increased mount and base stiffness for ultimate protection against mechanical shock as well as a robust double-coil filament designed to withstand severe vibration while remaining stable. Philips MasterDuty provides drivers with an increased lifetime of up to 500 hours.

See further and react faster with more light
Perfect illumination is especially important in the distance – usually between 75 and 100 metres in front of your vehicle. Philips MasterDuty boosts your visibility with more light on the road. This helps you recognise obstacles and any potential dangers earlier than with most other halogen headlight lamps.

A lifetime of safety so you can see and be seen
Every potential failure of a spare part is a risk for you and your vehicle. This is especially true for headlights. Every broken headlight lamp reduces visibility and safety for you and the oncoming traffic. Philips MasterDuty is optimised for a long and reliable lifetime. You can see and be seen for longer than with any other high-performance lamp.

Among the safest road-legal headlights
Philips MasterDuty is among the safest, easiest and most efficient way to upgrade your lorry or bus headlights within legal parameters. The lights are fully ECE certified.
