I wouldn't expect the "BMS" to affect the night-light function. Maybe whatever fried the BMS also damaged something else?

Many of the small "solar charge controllers" include switched outputs for lighting. Lights are off during the day, and can be programmed to shut off some hours after sunset or stay on all night. Other nice features are LCD voltage display, USB power for charging your devices. I got one a while back and used it to top up a bunch of old car batteries, powered from about 7 watts worth of solar panels. This one looks similar:

The problem may occur due to Incorrect Wiring a damaged controller or defective switch. I think further troubleshooting will be needed to find the actual causw.
