Capacitor in parallel with a resistor between live and full bridge rectifier
Welcome to Electrical Engineering!

The point of the capacitor is to limit the current through the full bridge rectifier. According to the “824J400V” indication, it is a 820nF capacitor. Its impedance at 50Hz is 3882Ω. It will limit the current to less than 62mA at 240V.

The point of the resistor in parallel is to discharge the capacitor when the bulb is disconnected.
