Low Gas Warning Light won't light up

Hi Guys! Need your help.

Aveo Hatchback 2009 1.2 MT

My low gas warning light won't light up.
The gauge is already past the red line.
It's already in contact with the stopper so I'm guessing it's almost empty.
Was able to drive 3-4kms more.

Still no light :(

I opened the dashboard already and confirmed that the bulb is working.

Please help. Any leads?

No clue on the light, but a fuel filter wouldn't be out of order now.

Mine works but its very dim/low.
