02 Avensis Dash Lights

[Toyota02]

Hey guys my 02avensis has begun giving strange eletrical activities.

It began with the reversing lights not turning off then the radio display light staying on

When the ignition key is removed also the radio will now stay on, the airbag light flashes 2 or 3 times when I stop the engine and now the warning buzzer for headlights on when I take my key out of the ignition has also stopped.

I have disconnected the Battery overnight to see if anything resets itself , but no joy.

The reverse lights is probably a switch problem but everything else is a mystery.

Any ideas ?????

[ents]

Most probably it is the ignition switch.
