how to modify stock taillights to meet uk requirements...
This could be a confusing but also helpful. SO I'LL DO MY BEST ...
1.) go to a place that installs trailer hitches ask them to figure out what each wire does that go into the back of the brake light bulb on the edge. since some cars require splicing of stock wires to tie into for aftermarket wire haness for a trailer hitch plug. this shoul be easy for them. if you figure that ouT, the rest is fairly simple.2.) you can disconect the ones that make the light blink and tie those into some new small blinker/running light wire harness plugs, that you can get at a local automotive store for pretty cheap. you can plug the matching amber light bulbs into these. they make little light harnesses that are just a rubber gromet. you would drill a small hole in the back of the reverse light/clear section of the tail light lense. Push the gromet in with the light plug wired to the correct wires you will have an amber blinker in the top (clear) section of you tail light and that should solve your problem. I would think with minimal labor charges and a help from a local trailer hitch shop you might be able to legally enjoy an edge in th uk. good luck!!! ill try to figure out wich wires are what for you since i just realized you dont have an edge yet. but ask around, maybe youll get lucky...
