Original NightEye A315 S4 H4 LED Headlight Bulb (2024 Model) – 6500LM White Light for Motorcycles & Cars

The NightEye A315 S4 H4 LED Headlight Bulb is a powerful lighting upgrade for vehicles that use the H4 socket, designed for the 2024 model-year. With advanced COB LED chips delivering around 6,500 lm per bulb (roughly 13,000 lm per pair), this bulb produces a bright, crisp 6,500 K white light that enhances visibility and gives your vehicle a modern lighting appeal. Its robust design includes high-speed silent fan cooling, an aluminium heat-sink housing and an IP68 rating (waterproof and dustproof), so it remains reliable even under harsh conditions. It supports a broad input voltage (DC 9-32 V) and operates across a wide temperature range (-40 °C to +80 °C), making it suitable for diverse riding or driving conditions. Installation is straightforward—if your vehicle has an H4 socket, this bulb is essentially plug-and-play—though correct alignment and secure mounting are important to ensure optimal beam pattern and prevent glare to other drivers. Overall, the A315 S4 offers a high-performance lighting solution for motorcycles and cars alike—offering brighter output, better durability, and improved nighttime visibility compared to standard halogen bulbs.
