What does HL stand for?

Explanation:
HL stands for Halon Fire Extinguisher. On aircraft, extinguishers labeled HL use Halon as the extinguishing agent, a clean, non-water option effective for electrical and avionics fires. The other terms aren’t correct because HL specifically denotes Halon, not a halogen in general, not “hazard light,” and not helium. Halon extinguishers are designed to suppress flames by interrupting the chemical reactions occurring in the flame.
