Junk item FX LED 1500 DX underwater light

Underwater light with high-brightness LED and battery level indicator.

- Model Name: FX LED 1500 DX

This item is being sold as junk.
There is a problem with the switch, and it is difficult to turn on. It only turns on after repeatedly operating the switch.
Would be great for someone who can repair it.
It can also be used for parts.

Accessories are as shown in the photos.

The battery terminals are dirty as shown in the photos, but this does not affect charging or lighting.

Thank you for looking.
