Product Specifications

H4 Yellow Vision halogen bulb features a standard P43t (P43t-38) base, rated at 12V with dual-power configuration: 55W for low beam and 60W for high beam. Fully compliant with ECE international automotive lighting standards, it is a professional high-penetration headlight upgrade solution that excels in both daily commuting and extreme low-visibility conditions such as heavy rain, dense fog and snow. Engineered strictly to original vehicle electrical and connector specifications, it requires no wiring modification or additional decoders, enabling direct replacement of OEM equivalent dual-beam bulbs. Easy to install, it offers broad compatibility with the integrated high/low beam systems of most passenger cars, SUVs, pickup trucks and some commercial vehicles.

Adopting premium UV-resistant quartz glass and precise golden coating technology, this bulb delivers consistent 3000K golden penetrating light. Its soft light color minimizes eye strain, while low light scattering and much stronger penetration than white/cool white light significantly improve the recognition distance of road markings, signs and obstacles in rain, fog, haze and dusty environments. This reduces driver fatigue during nighttime and harsh weather driving, thus greatly lowering accident risks. The reinforced molybdenum wire support structure and accurate dual-filament positioning ensure ECE-compliant beam pattern with a sharp cut-off line, eliminating glare to oncoming traffic. It also boasts outstanding vibration resistance, high-temperature tolerance and anti-aging performance, capable of withstanding long-distance rough roads and extreme heat exposure, ensuring a stable and long service life.

Certified with full ECE road compliance, the bulb provides uniform beam distribution without illegal stray light. Combining three key strengths—golden high penetration, efficient dual-beam performance and safety compliance—it is the ideal headlight choice for drivers prioritizing all-weather driving safety, especially those who frequently encounter foggy and rainy conditions.
