Question:
Can you mix and match regular lights with LED on the same trailer, or do you have to go all the way LED when replacing the tail lights?

Hey Bill! If you're switching from incandescent to LED lights like the # TN42XR it is best to convert everything to LED. However, it is possible to mix them and have it work. Sometimes it works, sometimes it doesn't, there isn't a particular rhyme or reason behind it it just depends on the trailer.
It looks like you already picked up this light and the passenger side # TN62XR. You can go ahead and install them and then test to see if everything works correctly. If you run into issues with some of the lights not functioning properly, I would go ahead and trade out your marker lights for LED.
