Dash Cluster questions

[1904Galant]

So I started to install some l.e.d's in my dash cluster, after pulling out the cluster i noticed that 3 bulbs have been removed by the previous owner


I know one is the TCL, but not sure whats setting it off ( bad wheel speed sensor? ) but i don't know what these other 2 lights belong to yet.

Ordering more l.e.d's for the car but here is what is going to look like

Shine a light in the empty spot and see what illuminates on the face side.
