Safety first: Remove the battery before opening any housings.

Check battery fit: Ensure the battery is fully seated and latched. A loose battery can cause voltage dips.
Inspect LED connections: Open the brush head or control panel where the LEDs are located. Check that the LED board connectors are firmly plugged in.
Examine wiring: Look for pinched or frayed wires leading to the LEDs. Replace the wiring harness if damaged.
Replace LED board: If flickering persists and wiring is sound, the LED board or its driver circuit may be faulty and should be replaced.

Cordless SEBO vacuum lights (headlights or indicator LEDs) flicker during use.
