M5 Series H4 Compact LED Headlight Bulbs

The CN360 M5 Series H4 combines four customized 3570 LED chips, 6500K white light, and active fan cooling in a compact headlight bulb. This version supports high and low beam operation, with a fixed mounting collar, non-polar connection, and a DC 12–24V operating range for compatible H4 applications.

Compact Design for H4 Headlamps

The M5 places its lighting blade, mounting collar, and cooling section close together in a compact replacement-bulb layout. The narrow emitting section sits above the mounting position, while the cooling structure remains integrated into the body. This arrangement helps keep the complete assembly manageable within a compatible headlamp housing.

The H4 collar is fixed and non-adjustable. Match the original bulb holder, connector, retention mechanism, and rear-cover clearance before fitting. The non-polar connection simplifies electrical polarity matching, while correct mechanical seating establishes the position of the LED section within the headlamp.

High and Low Beam Lighting

The M5 H4 provides separate high and low beam operation. High beam luminous flux is specified at 841.40 lm initially and 615.64 lm when stable, with corresponding power figures of 30.76 W and 24.69 W. Low beam output is 1,240.79 lm initially and 964.88 lm when stable, with power of 30.60 W and 24.71 W respectively.

The 6500K color temperature provides white illumination, and the listed beam angle is 360°. The complete headlamp optics shape this light into the road pattern. Check both beam modes and headlamp aim after installation so that the bulb and original optical assembly work together as intended.

Fast Heat Dissipation

An aluminum body and integrated cooling fan form the M5's thermal management system. Heat transfers through the metal structure toward the cooling surfaces, where the fan supports air movement. The finned body adds exposed surface area while keeping the cooling section within the compact bulb profile.

The cooling components work alongside the LED assembly during operation. Leave sufficient room around the rear section and keep wiring clear of the fan area. The headlamp cover should close normally without pressing against the bulb or obstructing its airflow openings.

Four Customized 3570 LED Chips

Four customized 3570 LED chips provide the light source for this H4 version. Their placement on the lighting blade works with the surrounding body structure to combine illumination and heat transfer in one assembly. The chip configuration supports the specified high and low beam functions.

The compact emitting section is positioned within the original headlamp's optical space. Reflector geometry, lens design, and bulb orientation all influence the final distribution of light. Selecting the correct H4 configuration and seating it securely helps maintain the intended relationship between these components.

Electrical Requirements for Vehicle Use

The operating range is DC 12–24V, with a specified input current of 2.6 ± 0.3 A at 13.5V. Match these electrical requirements to the intended vehicle circuit. The initial and stable output figures describe different operating states and should remain separate when assessing performance.

The original headlamp housing, cover, and seals remain part of the installation. Retain them where required by the vehicle assembly and confirm that the bulb, connector, and retention hardware fit correctly within the available space.

H4 Fitment within the M5 Series

Choose this version for a compatible headlamp requiring the H4 configuration. The original bulb specification, connector arrangement, and housing clearance should guide selection. After fitting, confirm normal high and low beam operation through the vehicle's controls. Secure mounting, unobstructed cooling, and correct beam alignment bring the mechanical, electrical, and optical parts of the installation together.
