Why Some countries Required 3800K-4300K Lens

Many countries require lenses to have a color temperature between 3800K and 4300K.Why does this rule exist?

As a professional bi led lens factory, we will fully explain the market standards and core advantages of this standard color temperature range.

Strict Legal Rules

The Eurasian Economic Union has unified vehicle compliance standards, limiting the legally permissible maximum color temperature for headlights to yellow or warm white.

Take Kazakhstan for instance: Fitting unapproved LED or xenon headlights counts as illegal modification of vehicle safety parts. Per Article 590 of the Administrative Offences Code, drivers face fines, forced lamp removal or vehicle seizure. While there is no formal ban on 6000K+ lamps locally, most garages stick to factory halogen-matching temperature lenses to avoid police penalties.

By January 2025, Kyrgyzstan saw 486 accidents linked to improper vehicle lighting. Officials now ban aftermarket LED/xenon retrofits in non-original lamp housings to cut traffic hazards.

Core Reason

OEM halogen headlights are manufactured with a color temperature about 3500K,the warm color.Traffic laws in most countries require aftermarket lenses to produce light spectrums close to the warm tone of factory original lamps, to avoid potential road safety risks caused by inconsistent lighting performance. Adopting high quality bi led lens that meets the 3800K-4300K standard is the key to compliant and safe vehicle lighting upgrade.

Climate Compatibility

Different color temperatures correspond to distinct wavelengths, which directly affects visibility during bad weather such as rain, snow and heavy fog.3800K–4300K warm white light features long wavelengths with gentle yellow tint. It barely scatters light in rain, fog and snow to maintain clear sight. Light sources over 5000K contain plenty of short blue wavelengths, which diffuse widely in damp, foggy air and reduce road visibility.

Advantages of 3800K–4300K for Night Driving

★Its spectrum mimics morning natural light and eases eye fatigue on long trips, bringing a Comfortable lighting effect for long-distance night driving.

★Low blue light output prevents harsh glare for oncoming drivers and cuts collision risks.
