Securely reconnect the rooftop, then turn ON the USB Power Bank to confirm
that all the lights installed are working OK.
Note: If you experience any issues with the lights not working and suspect an
issue with a component, please try a different port on the expansion board to
verify where the fault lies (with the light or expansion board). To correct any
issues with expansion board ports, please view the section addressing
expansion board issues on our
online troubleshooting guide.
