Sonic lipstick

The sonic lipstick was a device employed by Sarah Jane Smith sometime after she stopped regularly traveling with the Doctor. It presumably had qualities similar to the Doctor's sonic screwdriver.

It's shape allowed it to easily pass for an object a human woman would naturally carry. Like the Doctor's sonic screwdriver, The sonic lipstick could not open anything with a deadlock seal and unlike the Doctor's, it emitted a red light instead of a blue one. The device was weaker than the Doctors and was described by the Slitheen as a sonic disruptor.

Sarah Jane used it to send an electrical charge, cut cables and claimed she could destroy the Gorgon's portal key with sonic disruptions from the lipstick.

During the events of Journey's End, Sarah Jane used the device in order to get through a door to escape the testing of the reality bomb.

Continuity
It is possible that when River Song mentions a red setting on the Sonic Screwdriver, it refers to Sarah Jane's Sonic Lipstick. Although so far, nothing has been seen that differs from the Sonic Screwdriver.
