Exterior Lighting
Lighting Bezel & Lamp Housing
Modern LED lamps combine a cosmetic bezel, heat-loaded housing, aiming and attachment features, and a perimeter seal. Even with efficient LEDs, local thermal gradients and long exterior exposure can drive warpage, coating failure, condensation, and loss of optical alignment.

Component material package
A recommended grade per component, drawn from the Nexeo catalog. Recommendations are engineering assessments; a cited property links the choice to data we hold for that grade.
| Component | Recommended grade | Why |
|---|---|---|
Rear lamp housing Supports electronics, heat sinks, vents, and body attachments | Ultramid A3U42G6 Polyamide (PA66-GF30 FR) | A heat-stabilized glass-reinforced polyamide candidate supplies a stiff housing architecture around warm electronics and bolted interfaces. |
Decorative bezel Visible metallized or painted internal trim | Cycoloy C1200HF Polycarbonate Blend (PC/ABS) | A PC-ABS candidate combines molded surface quality and impact for a decorative bezel, subject to coating and lamp-temperature validation. |
Perimeter seal Controls water and dust ingress around the lens-to-housing joint | Santoprene 121-70W175 Thermoplastic Vulcanizate (TPV) | A TPV perimeter seal candidate supports molded geometry and assembly compression after weathering and compression-set validation. |

Validation & compliance path
- Applicable FMVSS 108 / UNECE lighting performance at the complete lamp level
- OEM exterior weathering, condensation, and thermal-cycle specification
- Flammability requirement where defined for the installed lamp zone
Engineering watch-outs
- Lamp photometry is an assembly result; resin selection cannot validate optical compliance.
- Metallization and paint bake can reveal molded-in stress or distort thin bezels.
- Vent strategy, seal compression, and permeation jointly control condensation.
