Features Common anode electrode means 2 color indicator lights share a Common Anode electrode. 2‑color LED lights emit uniformly, with a life span of more than 10,000 hours. High temperature flame‑retardant base, flame‑retardant in emergencies, enhanced conductivity of fire‑resistant wires. High‑accuracy CNC machine tool cutting technology, one‑piece metal shell has high structural strength, drop resistance and environmental protection. Ingenious design, built‑in sealing ring, and dustproof. Feature: 1. 2‑color LED lights emit uniformly, with a life span of more than 10,000 hours. 2.
