Small Light Connector by default always looks like it's in a push state (compared to the texture of a small connector) even though it's in a Mode:None.
Regardless of what mode it is in if it is not powered it will have a texture of a Push mode.

When the Small Light Connector is powered by forge energy it lights up and changes texture but it will always look like it's in Pull mode when powered.
To Reproduce
Place down a Small Light Connector and a Small Connector side by side.
Make sure you are wearing Engineer's Goggles to help you determine the mode the connector and the light are in.
Whilst standing above the blocks (if placed on the wall) Change the mode of a connector and the light to notice the change in texture of the Small Connector and lack of change from the Small Light Connector.
After seeing that the Small Light Connector always looks like it's in Mode:Push connect the Small Light Connector to a FE power source. After the Small Light Connector lights up you will notice that it will now look as if it's in Mode:Pull regardless of it's actual mode.
