Many times the issue with a dim light on one side or the other is caused by a poor ground connection. You will want to inspect all of the ground locations as well as the ground wires coming from each light. Check for loose connections or pinched or bare wires. Since you said it is a submergible light, check to make sure the light housing has not been damaged and no water has managed to get inside the housing.

If the lights on your trailer use a plug-in style pigtail harness look for damaged or bent pins.

If you have an aluminum trailer, make sure you have a ground wire run to all of the lights from the ground wire on the connector.

If everything checks out okay, you may just have a bad light and it will need to be replaced.
