Philips Diamond Vision HB4 (Twin)


Why buy me?

If you’re looking for headlight bulbs that offer a bright white light, look no further. These Philips Diamond Vision bulbs are the perfect option and are the closest styling match to HID Xenon bulbs. The deep blue coating on these Diamond Vision bulbs creates the ultimate white light with a slight blue tint.

Features and benefits

  • The colour temperature of these bulbs is 5000K
  • The colour and brightness of the headlights in the visual is not an actual representation of Philips headlights
  • The whitest upgrade available
  • The Philips Diamond Vision bulb does not offer a greater light output but provides a white light for enhanced styling
  • Philips Diamond Vision HB4 Bulbs are not road legal in the EU

PLEASE NOTE: The standard unit for colour temperature is Kelvin (K). Brightness is measured in lumen. Standard halogen bulbs produce yellow light at 3200K. Xenon HID technology produces white light at 4200K. The colour temperature for bluish white light is 5000K. The colour and brightness of the headlights in the visual is not an actual representation of Philips headlights. The Philips Diamond Vision range is not road legal in the UK. Philips Diamond Vision car bulbs do not comply with ECE R37 regulations and are not road legal. We are therefore not legally responsible for any future action relating to the use of these non-road legal bulbs if used on public highways or any other on-road situation.
