Cevap
The correct pairings align intermediate side markers (amber) with the midpoint, rear ID lamps (red) with the 3-lamp rear cluster, rear side reflectors (red) with the rear-most sides, front clearance lamps (amber) with the front corners, and the license plate lamp (white) with the rear registration mark.
The pairings correctly apply FMCSA lighting rules: front and intermediate components must be amber, rear components must be red, clearance lights show width (corners), identification lights show presence (center cluster of three), and the license plate requires white illumination.
