I bought these tail stocks with the intent of keeping the rear OEM tail light in place as I simply wanted more light out the back during running and braking. 50% of that came true as I have more brake lights lights. However the running lights do not work when coupled to the OEM incandescent brake lamp.
The problem: the running lights turn off as soon as the 1157 bulb is inserted. Why you ask? Because the stalks leak current between the run and brake LEDs. Now many of you will assume that I F'd it up somehow but I assure you that is not the case. Perhaps I bought two bad stalks and they are not designed this way but here is what happens if you try and integrate these combination turn indicators, running lights, and brake light onto a system with a dual element incandescent lamp (aka 1157 bulb) they bench test fine, everything works and then you place a path to ground like the +12V input to the brake light element of the 1157 bulb and the stalks running lights go off. One solution may be a replace the 1157 incandescent with a LED style bulb. Depending on its design, it may work but I don't have one handy. I also tried placing a diode and resistor to ground in a shunt configuration but this didn't help either.
Bottom line - these don't appear to do what I intended to do. Not to mention the Evotech supplied plate LED light is wimpy at best. I'm not sure what I'm going to do on that, but it will be changed in the future. I don't need pulled over for something stupid like that. A match is brighter than that LED.
Here are some pictures of the work done to wire these in. I kept all changes to the removable wire harness in the tail section.

We need to fix this mess into a harness

Turn signal adapter cables (3 wire, we need white and black).

White to Green or Brown for left and right turn. Black is Ground. Red is not used.

Pair out the left and right turns and solder

Slide shrink tube on and heat to do the shrink thing

Cover completed joints again
View attachment 41831
Pair out Ground, Run, and Brake lights. Solder, cover and heat to shrink

Completed assembly ready to be installed. This all plugs into the left side of the FZ with no mods to the OEM harness.

That will plug into this:

EDIT / Update: OK - I finally dug up functioning diode (new unlike the ones I tried) and walla - a simple 1N4001 diode in series with the BRAKE power to the stalks and it works!
