LED headlight bulbs Ledvance OSRAM H4/H19 12V 1400/1800 lm, 2 pcs

Ledvance OSRAM H4/H19 12V LED headlight bulbs (2 pcs) are replacement automotive lamps designed for vehicles that accept H4 or H19 fittings and operate on a 12 V electrical system. The pair delivers approximately 1400 lumens on low beam and 1800 lumens on high beam, producing a bright white light intended to improve forward visibility compared with standard halogen lamps. The bulbs are supplied as a set of two and are intended for use in beam configurations that match H4/H19 socket types.

Advantages

These Ledvance (OSRAM) LED bulbs offer a higher luminous output than many halogen equivalents while maintaining compatibility with standard H4/H19 sockets. Their bright white light enhances contrast and road detail at night and in low-light conditions, and the two-piece set allows simultaneous replacement of both headlight filaments for consistent beam colour and intensity. The design is focused on straightforward fitment for vehicles compatible with 12 V systems and H4/H19 lamp types.

Suitable for

• Passenger cars and motorcycles with H4 or H19 headlight sockets and 12 V electrical systems
• Drivers seeking increased forward illumination compared with halogen H4/H19 bulbs
• Cases where matching beam colour and intensity between left and right lamps is required

When it may not be suitable

These bulbs are intended specifically for vehicles with H4/H19 sockets and 12 V electrical systems; they are not compatible with vehicles that require other lamp types or different voltages. Some vehicle lighting housings, beam reflectors or headlamp electronics may be optimized for halogen filaments and can produce altered beam patterns or glare when fitted with aftermarket LED replacements. Check local regulations regarding headlight modifications, as LED retrofits are restricted or require homologation in some regions.

Key specifications

• Light output: approx. 1400 lm (low beam) and 1800 lm (high beam)
• Beam colour: bright white (manufacturer colour temperature not specified)
• Electrical system: 12 V DC
• Socket compatibility: H4 / H19 fitting
• Quantity: 2 bulbs per pack

How to use

Ensure the vehicle is parked, ignition off and headlights cooled before starting. Remove the headlamp cover according to the vehicle manufacturer’s instructions, extract the existing H4/H19 bulb and disconnect any connectors. Install the Ledvance LED bulb into the H4/H19 socket, ensuring secure seating and correct orientation for low/high beam function. Reconnect wiring and restore any dust caps or covers. After installation, test both low and high beam functions and check beam alignment to avoid glare to other road users. If the vehicle has headlamp leveling or adaptive systems, verify proper operation after fitting the LED bulbs.

What to consider before purchase

• Confirm your vehicle uses H4 or H19 sockets and a 12 V electrical system
• Verify local regulations on LED headlight replacements and required approvals
• Consider potential need for beam alignment or additional adapters/ballasts in specific vehicles

Usage recommendations

For safe and compliant use, replace both headlight bulbs at the same time to maintain uniform beam colour and intensity. After installation, check beam pattern and alignment on a flat surface and adjust if necessary to prevent dazzling other drivers. If unsure about fitment or compatibility with headlamp electronics, consult a qualified automotive technician or refer to the vehicle manufacturer’s guidance.
