The Point:
Upgrading your headlights to LED is no longer a legal “grey area.”
With the certified H11-LEDr technology, you can
finally enjoy elite visibility with 100%street legality across Europe.
1.Is Your LED Upgrade Actually Legal?
For years, car enthusiasts had a frustrating choice: stay with dim, yellow halogen bulbs or risk “Off-Road Use Only” LED retrofits that could result in heavy fines, failed vehicle inspections (MOT/TÜV), and dangerous glare for other drivers.The era of compromise is over. Thanks to new international safety standards,the H11-LEDr (LED Replacement) is now an officially recognized, road-legal alternative. But legality isn’t just about brightness—it is earned through
precision engineering.
2.What are the structural features of bulbs that comply with ECE R37 certification?
The Common Misconception:
Many drivers believe that the “cut-off line” (the sharp edge of light that prevents blinding others) is determined by the bulb alone.
The Reality:
The cut-off line is created by your headlight’s optics. However,for those optics to work, the light source must be in the exact same physical position as the original halogen filament.
The LEDOAUTO Engineering Breakthrough:
1.Geometric Equivalence:
Our H11-LEDr bulbs are designed to mimic the exact 3D coordinates of a tungsten filament. This allows your factory headlight to produce its intended, sharp cut-off line with zero glare.
2.The 3D Box System:
To pass street-legal certifications, the light-emitting area must fit within a microscopic “Box System.” If 90% of the light does not originate from that specific zone, itʼs not road-legal. Ours does.
3.Full Compliance:
Our solution is dual-certified under Regulation No. 37(Lighting Performance) and Regulation No. 10 (Electromagnetic Compatibility), ensuring no radio interference or dashboard errors.
3. Technical Comparison: EB Series vs Halogen！
Technical superiority is now verifiable. See how the certified AZMK H11-LEDr outperforms traditional halogen technology:
