# NAME

`led` — Generic LED driver

# DESCRIPTION

The `led` framework exposes controllable LED's through a sysctl(7) `hw.led` subtree. A value of 1 means that the corresponding LED is lit, and a value of 0 means that it is unlit. Writing a value of 1 will switch on the LED, and writing a value of 0 will switch it off.

# SEE ALSO

# HISTORY

The `led` driver first appeared in NetBSD 9.0.

# AUTHORS
