Here's a quick write up on how I did this mod. I will be updating it between today and tomorrow with part numbers and more details.

I started by removing the light, for Philips screws and it just pops out. Make sure you unplug the light harness in the back

 

I placed the bracket on the light and marked the holes with a white china marker. Becareful when drilling not to go too deep. There's a space between the light and housing.

 

After I drilled my holes I mounted the bracket to the housing and the led light to the bracket

 

I made a notch in the plastic for the wires, you can use a large drill bit or a round rasp.

 

After I wires everything, reinstalled the brake lights and enjoyed!

 

Here are some action pix

 

Very nice. How about some details on the wiring for us with limited wiring skills. Also, did the bracket come with the light?

 

Nicely done man. If I had to do it over again I wouldn't have put mine into the bumper. Your setup is way better.

 

What lights are those?

Edit: doh, never mind. It's really late.

 

Thanks man! There's no reason you can't still do this setup
