I have concluded my due diligence with this, and I will not be going ahead, for a few reasons.

Perone is correct in the wires he has selected. They are the ones that take voltage when the proper buttons are pushed. The green/white is the fog and the green orange is the brake.

The fog light when turned on is VERY bright. The dectane light has a dual row of leds as the outline of the triangle. By design, when the fog is illuminated, the few leds at the top and bottom become single row, so as not to be too much.

This mechanism which is achieved with two wires i believe, seems to complicated for my plain electrician skills.

Also, as I do agree that the brake looks a bit awkward with that inverse C design, I have turned on the Daytime Running Lights function from my PCM, and as a result the outline of the lights is always on, reducing the effect of the pattern of the brake light.

Below are visual aids which describe this whole situation.

BRAKE ONLY


BRAKE WITH LIGHTS ON


BRAKE WITH LIGHTS ON AND FOG LIGHT. Notice how the second row of lights in the middle goes out, leaving a single light. Perone, perhaps you are mistaken that the middle lights come off? Perhaps its only one row that does?
That Fog light is way too bright for braking...

 

Thanks for all your research...but I could never understand all the concern. Who cares what the guy following you sees?

 

Ha! What a great point! I guess we are all a bit twisted.
For the same reason why do I care if I have dual or single tips? Hmmm...
Certainly puts a few things in perspective. As always, good post!

 

Great work Nick and thanks for the effort.


Now, let's see some picture of your new behind Be great to see before (Rottec) and after

 

I just posted them in the relevant thread... HERE

 

So the conclusion is that it is not possible to have the full light patern on when braking?

 

I am sure you can, I am not sure I want to.
Firstly, the outcome is too bright, so it would be wrong.
Secondly, it is not an easy task to change the function to turn off some lights in the middle.

 

Yup - exactly what I do - set the daytime driving lights on (well actually in Canada it's mandatory) so the break lights fade nicely with the rest of the display. Doesn't bother me at all, and it's a MASSIVE improvement over the OEM nonLED and any other nonOEM LED on the market. What a mouthful :P

 

What do you mean? That is the only view 99% of the other drivers will ever see when my car is moving.

 

That is normal for the tail light even the stock does as well

 

Correct but OEM lights up "C" from the far edge by the fender and actually looks nice. Dectane is an inverted C and seems to end abruptly in the middle of the light. Regardless, looks much much better than stock.

 

i have cut the taillights.... i think it's all OK now... after photos

 

Awesome! Ordered mine

 

What do you mean? you found a solution?

 

Hey Perone, did you take your lights apart? pictures!!!!
