Have you searched for light already? In the SDK Help and/or the Wiki for example.

Class CHWRMLight may help you on this. see SDK for more info.

Apart from that if u also intend to avoid the screen light going off and keypad not getting locked, you can try setting inactivity timer like this:

User::ResetInactivityTime();

between what is your use case scenario here ?

[sbdavid]

I set 20 seconds for Power save time-out and Light time-out.
so my phone goes to black screen(power save mode) after 20 seconds if there is no user action.

scenario is following:
-my application is running.
-once application get any event(according to appliaction logic), screen should be light sothat user can see the application directly.

so I tested with CHWRMLight, but LightOnL does not work(LightOffL works well).

CHWRMLight* iLight;
iLight = CHWRMLight::NewL();

iLight->LightOnL( CHWRMLight::EPrimaryDisplay);

please let me know how I can do.
thanks.
