Not a particular DIY, rather show how simple and cheap is to this mode.
Final product :
Four strobes, four flashes, and solid on.

 

Step one, purchase one of these generics so called "GS-100A LED Brake Stop Light Strobe Flash Module Controller Box" from your favorite online place.
Mine cost around 7$ as I bought from a local supplier rather than half price from China.






Step two, twist negatives together and add a male connector to Reds.

 

Yea I used cheap Aluminium connectors, that was what I have on handbs and yes thy would make metallic reaction with brass.
Move to the car wiring on rise brake light/third/center brake light ignore Black as it is the negative, cut Black/Yellow and add two connectors, one female and one male/female( ******* lolll)




Ignore dirty fingers, I was changing spark plugs :D

 

By doing so you can remove the strobe/flasher whenever you need it in a matter of a second.
Now put flasher module inline on Black/Yellow wire, connect black to some grounds, I use tail lamps holding nut.
Ad isolation tape, heat shrink, PVC tape, Tesa tape, or what you normally use.
Enjoy!

I had to put the wiring on bypass for this year MOT as the brake light flashing/ strobe could be a failure.
Surprisingly it dropped engine check light with ABS related code like when the brake light switch is faulty loll
So... these aftermarket led tail lights would throw engine light but this probe mod prevent it all time :d
Had to put it on strobe spade pins and erase code and never comes back.
