Expert Reply:

Most likely you will not need to add any load resistors when installing the Optronics ONE LED Combination Trailer Tail Light # STL0016RB on your trailer. This should be a simple swap to replace your existing incandescent assemblies with this longer-lasting and brighter LED unit.

While most trailers can have their lights switched out for LED alternatives without missing a beat, there are cases where load resistors like # DI34ZR are needed but it's not something that can be accurately predicted beforehand. If you install the new lights and notice hyper-flashing on the assembly with the turn signals then it won't be too much trouble to add the resistors at that point to resolve the issue.

I just recommend waiting to see if they are needed before purchasing any load resistors.
