1939778 headlight is a direct-fit right-side headlamp assembly designed to fit vehicles compatible with DAF CF/XF Euro 6 platforms (2013–Present). The 1939778 headlight is commonly replaced when the lens is cracked, the housing is damaged, mounting points break after minor impacts, or moisture ingress causes unstable lighting output—helping workshops restore reliable visibility and reduce fleet downtime.
1939778 headlight is selected by OE reference to keep ordering accurate, because correct fitment depends on bracket geometry, rear connector position, adjuster alignment, and bulb/reflector layout. Before installing the 1939778 headlight, compare the old unit’s connector and mounting ears, route the harness with clearance, tighten fasteners evenly, and re-check beam aim after fitting to keep the pattern stable during long-haul vibration and frequent washdowns.
