Lampade LED per fari Ledvance LEDriving XTR H4 64193DWXTR, set da 2

Set of two Ledvance LEDriving XTR H4 LED headlight bulbs engineered as direct replacements for H4 halogen bulbs. These LED units offer a consistent light output and longer service life compared to conventional halogen lamps, and are intended for vehicle headlight applications where LED conversion is permitted. The compact design matches the H4 fitting and provides focused beam geometry to support road illumination and driver visibility under compatible housings and regulatory conditions.

Advantages

The Ledvance LEDriving XTR H4 bulbs deliver stable luminous performance over extended operating hours and consume less electrical power than standard halogen equivalents. The bulbs are manufactured for thermal stability, helping to maintain light output and colour consistency during typical driving conditions. Their plug-and-play form factor simplifies replacement in housings designed for H4 fittings, reducing installation time when vehicle compatibility and local regulations allow LED retrofitting.

Suitable for

• Replacement of H4 halogen headlight bulbs in compatible vehicles
• Drivers seeking improved visibility and more consistent light output
• Road illumination where LED headlight conversions are permitted by law
• Applications requiring bulbs with longer rated service life than halogen

Key specifications

• Socket type: H4 fitting compatible with standard H4 housings
• Light source: LED technology with integrated emitter modules
• Set quantity: two bulbs for full low/high beam replacement
• Beam behaviour: designed for directional beam pattern in H4 reflectors/lenses
• Power and efficiency: lower power consumption compared to halogen equivalents (specified by manufacturer)
• Durability: extended operational lifetime relative to halogen lamps

How to use

Before installation, verify vehicle compatibility and legal allowance for LED headlight replacements in your jurisdiction. Park the vehicle on a level surface, switch off power, and let the existing lamps cool. Remove the headlamp unit or access the rear of the headlight assembly according to the vehicle manufacturer’s instructions. Extract the H4 halogen bulb carefully and replace it with the LEDriving XTR H4 bulb, ensuring correct alignment of the H4 base and secure seating in the socket. Reassemble any removed components and test beam function and aim at low speed to confirm correct alignment and operation. If the vehicle requires a CANbus adapter, resistor, or coding for proper operation, follow the vehicle manufacturer’s guidance or consult a qualified technician.

Recommendations

Use these LED bulbs only in compatible H4 housings and where LED retrofits are permitted. After installation, verify beam alignment and adjust the headlight aim if necessary to avoid glare for other road users. For vehicles with electronic control systems that monitor bulb operation, confirm whether additional adapters or coding are needed to prevent errors. If in doubt, seek professional installation to ensure compliance with local road regulations and safe beam pattern performance.
