A popular choice for updating Freightliner cab lighting is the 20?diode amber LED cab marker light, designed as an aftermarket replacement that adds a classic rippled exterior lens. This cab light measures about 4.5?inches long by 2.25?inches wide and 2.25?inches high, making it suitable for many Freightliner Century, Columbia, Coronado, Classic and FLD models from the late?1980s through the 2010s, depending on the option selected. It uses 20 amber LEDs with a polycarbonate lens that resists cracking and damage, and the unit is sold individually with a warranty against defects in workmanship and materials from the date of purchase, though it is not an OEM component. Because this marker light is offered for specific model fitments, checking compatibility with your truck before ordering is recommended to ensure correct installation and function.
