What approach lights are available for the ILS RWY 25L approach at LAX?

The correct approach lights available for the ILS RWY 25L approach at LAX are indeed ALSF-2 with sequenced flashing lights. ALSF-2 (Approach Light System with Sequence Flashing Lights) is specifically designed for precision instrument approaches and enhances visual guidance to the runway. It consists of a series of lights, which illuminate the approach path to the runway and provide pilots with additional visual cues as they transition from instrument flight to visual flight.

The sequenced flashing lights feature prominently in ALSF-2 systems, creating a sequence of lights that help pilots better gauge their distance from the runway and enhance their orientation in low visibility conditions. These lights improve safety during the landing phase by making the runway more visible.

Other options mentioned do not apply to the ILS RWY 25L approach at LAX. For example, while MALSR is a type of approach light system, it is not typically used for this runway. The mention of HIRL and TDZ/CL relates to runway lighting rather than approach lighting specifically for a precision ILS approach. VASI and PAPI refer to visual approach slope indicators, which are useful for providing glide path information but do not constitute the primary approach lighting system for an instrument approach like
