Question about turn signal red/orange

Hi,

I have a Lumina in Germany, and bought another one.
Now I must replace the red turn signal in orange one, and now I need some opinions...

This one (http://cgi.ebay.de/ws/eBayISAPI.dll?ViewItem&item=230437705269&ssPageName=STRK:MEWAX:IT) I found on eBay, and I would put it under the red turn signal between bumper and lamp.

Did anybody have another ideas?
And how can I cut the electrical line between brake light and turn signal lamp, that not if I brake the orange turn signal lamps goes on.

Thx.

Since the LEDs are low current, the easiest/best method may be add wiring along the rear body harness and power the LEDs from the front turn signal circuits.

It's easier if I let the turn signal cables, and make a new cable from brake switch?
