Nathan, the most common cause for a dim turn signal is a weak ground. I recommend checking your grounds and make sure they are attached to a clean, bare metal surfaces that is free of dirt or corrosion. You should also make sure that each of the individual light grounds are secure as well.
If you're still having issues once you check that, feel free to come on back and we can keep troubleshooting.
