H4 LED Headlight Conversion Kit — 20000LM Mini Projector Lens

Three pillars of next‑level illumination

• Mini projector lens technology

  A compact internal mirror reflector mimics a full-size projector, shaping a beam that’s wide, even, and razor-sharp at the cutoff. You see the road, not the tops of trees.

• Canbus error‑free integration

  Built-in canbus decoder eliminates dashboard warnings and flickering. Compatible with 12V and 24V systems, left or right-hand drive. No extra resistors, no splicing.

• Dual‑beam simplicity

  Keep your factory hi/lo control — the bulb physically shifts focus when you switch. Low beam throws broad coverage, high beam reaches deep down the road. One bulb does it all.

Measurable output, measurable confidence

• 20000LMTotal output per pair at 6500K
• 90WRated per pair — efficient, not hungry
• 12–24VWorks on nearly every passenger vehicle
• sharp. crispZ-shape cutoff prevents glare

Install in three steps

1. 1
   Remove the old bulb

   Open the hood, locate the back of the headlight housing, and remove the dust cap (if equipped). Disconnect the electrical connector, then unlock the metal retaining clip and gently pull out the halogen bulb. Do not touch the glass of the new LED bulb with bare fingers — use the towel or wear gloves.

2. 2
   Insert the LED bulb

   Slide the AILEO bulb into the housing, matching the H4 tab orientation (typically with the projector lens facing forward and the heatsink fins facing outward). Secure it with the factory retaining clip, then connect the bulb’s plug to the canbus module’s input side. Connect the canbus module’s output to the factory harness.

3. 3
   Test and tuck

   Turn on the headlights to confirm hi/lo beam switching works and that the beam pattern looks clean on a wall 25 feet away. If the cutoff is blurry, rotate the bulb slightly within the housing until you see a sharp Z-shape. Tuck the canbus module and wiring inside the housing, replace the dust cap, and you’re done.

Every driver knows that moment of doubt

The halogen headache

Yellow, weak, and unfocused. Factory bulbs barely light the shoulder, let alone the deer 200 feet ahead. Replacement bulbs cost less than a dinner out, but they burn out fast and never get bright enough. You deserve headlights that match the speed of your life.

The projector difference

AILEO mini projector lenses focus every lumen into a tight, wide beam with a sharp cutoff. No scatter into oncoming traffic — just clean, usable light exactly where you need it. The canbus decoder talks to your vehicle’s computer so there’s no flicker, no error, and no hyper-flash.

From dusk to dawn

Install in 30 minutes. Turn the key. The road ahead transforms — signs become legible a quarter-mile out, the shoulder reveals every detail, and your eyes relax because the beam feels like daylight. Overtake with confidence, navigate winding roads, and arrive at every destination less tired. No compromises, just clear vision.

Compact yet powerful

• 111 mmHeight
• 36 mmTop diameter
• 47 mmBase width
• 194 gWeight per bulb

Roughly the size of a medium marker pen. Check your housing depth: the heatsink base extends 47mm behind the socket.
