GR, here's a quick rundown of Lamonster's Tail Brightener Kit installed in my 2017 F3T with factory top box.
What's in the package:
The instructions:
The tail light you'll be removing, looking down from the top with the top box lid open:
Retention pins removed and light flipped over to expose plug:
Now, here's where I ran into issues. The included brake light flasher module would not work on my F3T. I ordered the top box after purchasing the Spyder, maybe the wiring is different. However, the end result is that the flasher harness would not work in my installation. Given the inexpensive price of the kit, I went ahead and installed it without the flasher module harness. YMMV.
I cut and stripped the top box tail, brake and ground wires, reconnecting them with the Leverlocks included in the Lamonster kit. After positioning, preparing and installing the two upper LED strips, I stripped back about 2" of the outer jacket of the LEDs wiring and stripped about 1/4" from the individual wires' insulation. The wires were then twisted together by color and inserted in the Leverlocks. Note that the wiring colors do not correspond as the instructions say they should. Since each of the two rows of LEDs are of equal brightness, it doesn't matter which way they go in this installation. The excess wiring and Leverlocks fit easily into the space under the tail/brake light. Reinstalled the top box light, ensuring that the tabs on the bottom of the light housing engage the top box, insert and press the locking pins into place and it's done!
The same procedure would be used to connect the lower LEDs - I chose to only install two for the moment. You will note in the instructions that the wiring on one lower LED strip needs to be reversed "to maintain symmetry". That way, if you have the lower strips mounted vertically as the instructions call for, you won't have the left side of both strips as the tail and both right sides as the brake.
As I said, I've only mounted the upper pair of strips for the moment. Here's what they look like in tail light mode; they're quite a bit brighter than the factory tail lights. In addition, as Revjames notes the LEDs are closer to drivers' line of sight. I also like that they extend around the sides of the top box as the F3T/L is seriously deficient in side lighting IMO.
