A neon lamp originally designed for alternating current, unlike, for example, ІН-1, ТН-0.3-3 or ІН-3. Nevertheless, direct current neons were widely used on alternating current, even though this is an unusual mode of operation.
When operating the indicator on direct current, polarity must be observed: the anode is connected to the base body, the cathode is connected to the base contact.
