High pressure sodium lamp in the next interview is good, and on top of not light, what is the matter?
The upper wire is not connected, the light port is not in good contact with the sodium lamp, and the voltage at the top of the lamp is low.
The interface is estimated to have been sent. This kind of thing often happens. Take apart beforehand and check all the connections. No problem with test light. Wrap a packet with adhesive tape. The key is to wait for the lamp to cool down and install.
The lamp is bright and the filament is hot. It may break or fall loose. Maybe it'll be all right. Just fix it again. Usually light bulbs.
