Acting as the "starting" element to ignite the gas inside the bulb.

The DB2 behaves like a "transistor without a base". It remains in a non-conductive state until the applied voltage exceeds its specific breakover threshold. Once triggered, its resistance drops sharply (negative resistance characteristic), allowing a pulse of current to flow to the gate of a TRIAC.
