A pair of H4 LED retrofit headlight bulbs from Philips, the 11342ULX2 Ultinon Compact delivers up to 160% brighter light output compared to standard halogen, 6000K colour temperature for a crisp white light appearance, compact design for improved fitment in tight headlight compartments, long life construction, and is designed specifically for use in reflector headlight systems. Sold in pairs.
The Philips 11342ULX2 is the H4 fitment in the Philips Ultinon Compact LED range, providing a direct retrofit upgrade from standard H4 halogen bulbs to LED performance in vehicles fitted with reflector-style headlight housings. The Ultinon Compact delivers up to 160% more light output than a standard halogen bulb in the same fitting, with a 6000K colour temperature producing a bright white light that improves road illumination and visibility during night driving.
The compact design specifically addresses the common fitment challenge of LED retrofit bulbs in vehicles with tight space behind the headlight unit, reducing the likelihood of clearance issues with dust covers and housing components during installation. Designed for reflector headlight systems only. Not suitable for projector headlight systems, where the optical geometry requires a different light source position and distribution pattern.
Up to 160% Brighter Light - Significant Visibility Improvement: Delivers up to 160% more light output compared to a standard halogen H4 bulb in the same fitting, providing a significant improvement in road illumination and driver visibility during night driving.
6000K Colour Temperature - Crisp White Light: The 6000K colour temperature produces a crisp, cool white light output that improves contrast and visibility compared to the warmer yellow output of standard halogen bulbs.
Compact Design - Improved Fitment in Tight Compartments: The compact LED driver and heatsink design reduces the physical footprint behind the headlight unit, improving fitment compatibility in vehicles with limited clearance behind the headlight housing.
Long Life Construction: Long life LED components reduce the frequency of bulb replacement compared to standard halogen bulbs.
Reflector Headlight Design - Direct H4 Retrofit: Designed specifically for reflector headlight systems as a direct drop-in replacement for standard H4 halogen bulbs.
Sold in Pairs: Supplied as a pair for complete front headlight replacement in a single purchase.

The 11342ULX2 suits vehicles with H4 headlight bulb fitment and reflector-style headlight housings. Not suitable for projector headlight systems. Confirm your vehicle's headlight bulb fitment type and headlight housing style before purchase. Confirm physical clearance behind the headlight dust cover for LED retrofit installation in your specific vehicle before purchase.
Are the Philips 11342ULX2 suitable for projector headlights?
No. The 11342ULX2 is designed for reflector headlight systems only. Projector headlight systems require a different light source position and optical distribution pattern that is not compatible with this reflector-optimised LED bulb design.
What does 160% brighter mean for the 11342ULX2?
The 160% brighter figure represents the increase in light output compared to a standard reference halogen H4 bulb in the same fitting. This means the road ahead is illuminated significantly more intensely, improving visibility and reaction time during night driving.
What colour temperature is the 11342ULX2?
The 11342ULX2 produces a 6000K colour temperature, which is a crisp, cool white light with a slightly blue-white appearance compared to the warmer yellow tone of standard halogen bulbs.
Will the 11342ULX2 fit vehicles with tight headlight compartments?
The Ultinon Compact is specifically designed with a compact form factor to improve fitment in vehicles with limited clearance behind the headlight housing. Confirm available clearance behind the headlight dust cover in your specific vehicle before purchase to ensure compatibility.
How many bulbs are included in the 11342ULX2 pack?
The 11342ULX2 is sold as a pair, including two H4 LED bulbs for complete front headlight replacement.
