H4 halogen bulbs, rated at 12 V 60/55 W and ECE approved. Supplied as a matched pair with P43t socket compatibility.
Safer night driving – thanks to broad beam spread
The H4 12 V 60/55 W halogen configuration supplies both dipped and main beam functions from a single lamp, producing a wide illumination area. P43t fitting positions the filament and glass to shape a consistent beam pattern.
Improved visibility in low light helps reveal road details sooner and reduces the strain of long night journeys.
Balanced output over time – with matched-pair bulbs
Each pack contains two H4 lamps manufactured to the same specification so both headlamps begin with comparable luminous performance. Similar manufacturing tolerances mean both bulbs tend to age at comparable rates.
Replacing both sides together prevents uneven light levels and reduces the chance of a quick return to the garage for a second replacement.
Quick fit and compliant use – with P43t socket and ECE approval
P43t socket design allows direct insertion where H4 lamps are specified, avoiding adapters for compatible vehicles. ECE approval confirms conformity with recognised European lighting standards.
Fast installation into compatible cars and confidence that the lamps meet road-legal requirements for many markets.
