51117954253 Fog Lamp Trim - OEM-Spec Frame Enhancement for BMW F49 X1 LCI

Precisely engineered for BMW F49 X1 LCI fog lamp integration, the 51117954253 and 51117954254 trim strips provide seamless aesthetic continuity with bumper contours. These ASA polymer components feature UV-stabilized surface treatment that maintains color consistency within ΔE<1.5 under prolonged sun exposure. The three-dimensional rib structure behind the visible surface ensures dimensional stability across temperature fluctuations (-40°C to +95°C). Precision-molded clip locations maintain 0.2mm assembly tolerances for rattle-free operation, while the textured finish replicates OEM surface patterns at 120-150μm roughness depth. Installation requires no modification to existing lamp assemblies, preserving original mounting points through slide-lock engagement mechanisms.

Advanced Material Engineering

The 51117954253 trim strip utilizes injection molding techniques that achieve 0.05mm/mm thermal expansion coefficients, ensuring dimensional harmony with adjacent metal components. Fifteen structural ribs running perpendicular to the visible surface create impact resistance up to 15J while maintaining 2.3mm wall thickness consistency. The surface treatment process applies dual-layer UV protection: a base layer with light-stable pigments and a topcoat delivering 92%+ gloss retention after 3,000 hours xenon testing. Clip housings incorporate 316-grade stainless steel inserts that withstand 50+ installation cycles without deformation. Rear ventilation channels prevent moisture accumulation while maintaining aerodynamic efficiency within 0.5% drag coefficient variance.

Vehicle Integration Specifications

Designed exclusively for BMW F49 X1 LCI models, the 51117954253/51117954254 pair accommodates all factory fog lamp configurations including LED and halogen variants. Verified compatibility covers M Sport and xLine bumper profiles across global market specifications (NA, EU, Asia). The trim maintains 8mm clearance from parking sensor arrays and 12mm from radar modules in ADAS-equipped vehicles. Precision color matching ensures ΔE<2.0 variance against original bumper finishes in all 40+ BMW factory colors. Installation compatibility confirmed for vehicles with factory-installed front splash guards or auxiliary lighting systems.

Compatibility Assurance

Compatible with BMW F49 X1 LCI vehicles requiring fog lamp frame enhancement components. Proper installation should follow vehicle manufacturer technical guidelines for accessory integration.
