9438201561 Mercedes Headlight | Precision Beam Alignment Solution
9438201561 Mercedes Headlight
Designed for "precision beam pattern alignment in commercial vehicle operations", the 9438201561 Mercedes Headlight (9438201561) features adaptive projection optics for 2002-2021 Actros MP2/MP3 trucks. The hybrid polycarbonate-glass construction combines impact resistance with UV-stable light diffusion, addressing "lens yellowing in extended service". Integrated thermal management prevents condensation through pressure-equalized venting, while the modular bulb housing accommodates W5W, PY21W, and H7 configurations. Precision-cast adjustment gears maintain ±0.5° beam alignment accuracy across 1.5 million vibration cycles.
Multi-Configuration Compatibility
Engineered to resolve "model-specific beam dispersion issues", the optical system adapts to both LHD and RHD configurations through reversible lens indexing (9438206461/A9438201561). The 24V circuit architecture prevents voltage spikes with integrated surge protection, compatible with CAN-based lighting systems. Three-stage sealing protects against dust ingress (IP6K9K) while maintaining thermal conductivity for LED conversions. The universal mounting bracket accepts both spring-loaded and bolt-on retention systems, with color-coded wiring harnesses for H1/H7 bulb variants. All components meet ECE R112 photometric requirements for commercial vehicle lighting.

| Lens Assembly | UV-treated polycarbonate | ECE R112 |
| Housing | Glass-fiber reinforced PA66 | ISO 16750-3 |
The rotational adjustment mechanism provides ±15° horizontal and ±5° vertical beam control, with laser-etched alignment markers for precise calibration. The 9438201561 assembly integrates with rain/light sensors through standardized 6-pin connectors, while the anti-glare reflector pattern reduces stray light by 40% compared to conventional designs. All sealing surfaces use compression-molded EPDM gaskets rated for -40°C to 135°C thermal cycling. The modular design allows individual replacement of lens, housing, or reflector components without full assembly removal.
