Flickering Lights
That concerns me on two points.
One is that single 18 gage connection is carrying load to three 18 ga wires. That might be OK knowing the loads are actually pretty low.
The other concern is having no strain relief with three wires. Maybe if they are supported it would be OK.
Another approach is:
Two wires on a standard open barrel female terminal.
Use a piggyback to add more.
OR.
Make a single 16 ga wire connection to the terminal.
Then make a junction in a location where the wires all have good support and not subject to a tight bend or turn.
Inline wiring splice clips........from the Dodge RAM service manual
There are also techniques for wrapping the wires and soldering in a branch.
edit:
Here's an example where there was improper wire support and an improper solder splice.
Solder and Poor Trouble Shooting = $$$$ - Marine How To
I'm not against soldering wire, just wanted to point out that these sort of problems are real.
