Electrical System Issue?

I need help figuring out why the lights and turn signals on the passenger’s side are a lot dimmer than the driver side. Also, when driving at night I can see a slight glow from the passage side (dim side) hood mounted turn signal.

I have tried switching a few bulbs around and checked/cleaned a few grounds around the lights, but I really don’t know how to narrow in on what is causing the issue… any suggestions???
