The Head Lamp LH (Left Headlight Assembly) with OEM numbers 8978550044 / 8-97855004-4 is a verified direct-fit replacement for ISUZU ELF / NPR94 Forward series light trucks. This headlight assembly provides forward road illumination for night driving and adverse weather conditions to ensure driving safety.
The headlight assembly consists of a reflector, lens, bulb socket, and electrical connector. When activated, current flows to the H4 bulb, which emits light focused by the reflector and refracted by the lens to produce compliant low-beam and high-beam patterns. Features an angle adjustment mechanism for beam angle adjustment based on vehicle load conditions.
