Intermittent Loss of Panel Lights and Signal Lights on Bajaj CT100

What could be the possible problem with my Bajaj CT100? When the motorcycle is running, it has a panel with indicators, such as the N (Neutral) light when the gear is in neutral and the left/right signal indicators when the turn signals are activated. However, there are times while I am already riding that the panel lights suddenly turn off and the signal lights also stop working, but the engine continues to run normally.

I need to turn the key off and then turn it back on again before the panel lights and signal lights work properly again. However, the headlight remains working even when the panel and signal lights stop working. The motorcycle battery is also brand new.

What could be the possible cause of this issue?
