Halogen bulb Neolux H4 Blue Power Light 2-pack — 12V, 100/90W

Neolux H4 Blue Power Light 2-pack contains two H4 halogen headlight bulbs designed for 12V vehicle electrical systems. Each bulb provides a dual-filament 100/90W output to deliver both high-beam and low-beam functions in lamps built for the H4 format. The bulbs are intended as direct replacements for worn H4 units in cars and light vehicles, offering standard beam geometry and conventional single-base fitment for compatible headlamp housings.

Advantages

The Neolux H4 Blue Power Light bulbs combine a familiar H4 dual-filament design with a 100/90W power rating to restore headlight performance in vehicles originally equipped for H4 lamps. Their construction follows standard dimensions and pin arrangement for straightforward installation, and the blue-tinted appearance of the envelope is engineered to influence the light color while keeping the electrical and optical characteristics compatible with common halogen reflector and projector housings.

Suitable for

• Replacement of aged or failed H4 halogen bulbs in passenger cars and light commercial vehicles
• Vehicles with 12V electrical systems designed for H4 (dual-filament) lamps
• Drivers who need a direct-fit, conventional halogen solution without wiring or adapter changes

When it may not be suitable

This product may not be suitable for vehicles requiring bulbs with a different wattage, base type, or single-filament configuration. It is not a plug-and-play upgrade for cars that require low-power or LED retrofit solutions, and it may not be compliant with local regulations if higher-wattage bulbs exceed permitted specifications.

Key specifications

• Bulb type: H4 (dual-filament)
• Nominal voltage: 12 V
• Power: 100 W (high beam) / 90 W (low beam)
• Pack quantity: 2 bulbs
• Fitment: standard H4 single-base with three-prong connector
• Light appearance: blue-tinted envelope designed to influence color temperature

How to use

Before installation, turn off the ignition and allow the headlight assembly to cool. Access the headlamp housing according to your vehicle’s service instructions, remove the electrical connector and the bulb retaining mechanism, then extract the old bulb. Install the Neolux H4 bulb by aligning the three-prong base into the socket and securing the retaining clip or cap. Reconnect the electrical plug and test both low and high beams to confirm correct operation and beam alignment. Avoid touching the glass envelope with bare hands to prevent premature failure from oils or contaminants.

What to consider before purchase

• Confirm your vehicle requires H4 (dual-filament) bulbs and accepts 100/90W power ratings
• Check local regulations regarding permitted bulb wattage and color modifications
• Verify physical fitment in your headlamp housing and that no additional adapters are needed

Recommendations

For reliable performance, replace bulbs in matching pairs and inspect headlamp reflectors and lenses for damage before installation. If beam alignment or glare issues occur after fitting, have the alignment checked by a qualified technician to maintain safe road illumination and compliance with local lighting rules.
