Jeep TJ LED brake light wiring help

Hi everyone. I need some help with LED brake light wiring. I have a 2004 Jeep TJ. The Brake lights have the following wires

(Drivers Side) Green/Red
(Passenger Side) Brown/Red

I bought some LED brake lights with 4 wires


When I wired it together, everything works fine but the second I turn on my headlights, everything turns off. Here is how I wired.

Black/Yellow - Black wire
Purple/Black - White wire
Green/Red - Red and Green wires
Brown/Red - Red and Green wires

Not sure if this is correct. Only one I know is correct is the white wire to the purple/black. Any assistance to this problem is greatly appreciated.

There are lots of manufacturers of LED lights. We have no idea which manufacturer or what product you are dealing with.
What advice did the manufacturer, their web site or the product instructions give?

The stock wires are as follows:
Left assembly
VT/BK - reverse lamp
DG/RD - turn/stop lamp
BK/YL - parking lamp

Right assembly
VT/BK - reverse lamp
BR/RD - turn/stop lamp
BK/YL - parking lamp
DG/RD - left turn/stop lamp (used for trailer harness feed)

As to which colour wire connecting to which stock wire, that would depend upon the instructions that came with the LED lamps and what the purpose of each wire is.
