Compact Fit
Short rear structure designed for lamp housings with limited installation clearance.
Fanless Reliability
Passive aluminum cooling with no fan noise or moving cooling parts.
Fan-Cooled Output
Active cooling supports higher operating power and more stable output after warm-up.
Weather-Ready Colors
Selected configurations can be developed in white or warmer/yellow color temperatures according to market demand.

Important Note: H3 availability and specifications vary by series. All published power and lumen values must identify whether they are measured per bulb or per pair, and whether lumen output is initial or stabilized. Request the latest H3 datasheet for final confirmation.
What Makes an H3 Bulb Different?
H3 is a single-beam bulb format built around a PK22s mounting base. Unlike bulb types with two terminals integrated into a plastic connector, a conventional H3 structure commonly uses a fixed lead wire for one electrical connection, while the mounting/base arrangement forms part of the installation and electrical system.
An H3 bulb may be used for high beam, low beam, fog light or auxiliary driving light depending on the lamp assembly. The socket name alone does not determine the lighting function.
PK22s Mounting Base
The base shape and locating features must seat correctly in the H3 lamp holder to maintain the intended light-source position.
Single-Beam Light Source
H3 performs one lighting function in a given lamp. It is not a dual-beam bulb like H4.
Lead-Wire Connection
The wire length, terminal style, polarity and available routing space should be checked before bulk purchasing.
Compact Housing Requirement
Many H3 fog and auxiliary lamps have limited internal depth. Bulb body diameter, heatsink length and driver placement can determine whether the rear cover closes.
*Reference: The H3 halogen format uses a PK22s base (OSRAM / UNECE R37). LED retrofit dimensions and homologation must be checked by individual product and market.
One H3 Socket, Different Lamp Applications
H3 describes the bulb interface, not a single universal lamp position. Depending on the vehicle and headlamp design, H3 may appear in several applications.
High Beam
Used in selected separate high-beam reflectors where concentrated forward illumination is required.
Low Beam
Found in selected older or specialized headlamp assemblies. Beam alignment must be checked.
Fog Light
A common H3 application. Compact fit and controlled beam distribution are highly useful here.
Auxiliary Lamp
Used in selected off-road, commercial, motorcycle and aftermarket auxiliary lamp assemblies.
Fitment notice: Always confirm the original bulb code, base, housing depth, wiring connection and intended lamp function. The vehicle model name alone is not sufficient because different trims and headlamp assemblies may use different bulb types.
Four Checks Before Ordering H3 LED Bulbs in Bulk
Confirm the PK22s Base
Check the original bulb and lamp holder. Do not assume H1, H3 and H3C are interchangeable because their mounting and electrical arrangements differ.
Measure Rear and Internal Space
Confirm the maximum bulb diameter, total length, heatsink clearance, driver location and whether the rear cover can close.
Check the Lead Wire and Polarity
Verify terminal type, wire length, ground path and polarity. A polarity-free driver can simplify installation, but this must be confirmed on the selected model.
Test the Actual Beam and Electronics
Install samples in representative vehicles to evaluate beam distribution, operating temperature, dashboard warnings, flicker and radio interference before mass production.
Need Help with H3 Fitment?
Send us your original H3 bulb photo, lamp-housing dimensions and target vehicle market. We will recommend suitable samples for fitment testing.
Designed Around the Original H3 Light Center
High lumen output does not automatically produce a useful beam. The LED emitting surface must remain close to the position and size of the original H3 filament so the reflector or projector can distribute light correctly.
LEZEN evaluates chip position, board thickness, mounting-base accuracy and bulb orientation in compatible H3 housings. Final performance should be verified through a wall-beam test in the target lamp assembly.
-
Thin Emitting Surface A controlled distance between the two LED emitting surfaces helps approximate the compact halogen filament and reduce scattered light.
-
Accurate Base Position Stable PK22s seating helps keep the light source at the intended focal point.
-
Housing-Level Beam Test Samples should be tested in the buyer's representative fog, high-beam or auxiliary lamp because optics differ among housings.
Stable Output Matters More Than Initial Brightness
LED output changes as operating temperature rises. A meaningful H3 evaluation should record power, temperature and lumen output after warm-up—not only the first seconds after switch-on.
Depending on the product level, LEZEN can provide passive aluminum cooling, compact fan cooling and enhanced thermal-conduction structures. The correct solution should balance output, housing space, noise, durability and target price.
