New LED brakelight install question

Got the LED 3rd brake light from thespeedline.us and installed no problems ( looks great, LED color matches perfect). I have not hooked up the running light feature yet though because I'm not sure where to hook it into. The directions say to connect to the orange wire running lamp; which I'm guessing is the one going to the LED section of my tails? I never go just by color when it comes to electrical work. Speedline's "support" is weak at best, so I'm wondering if anyone knows about the wires in the tail. I see 3 wires(black,purple, and orange) but I dont know for sure which is which. Has anyone tried tapping into these or know which wire carries what? Any help is greatly appreciated.

Re: New LED brakelight install question

It depends on what you want to do. First, which led light are you talking about?



If it's #1, there should be a white plug on the led housing, that plugs directly into where the stock incandescent bulb goes.



#2, or 3, you need to tap the wire into the brake/running lights. Top circle, orange wire. If you want it to only go on when your brake, use the red with blue wire, etc.

Re: New LED brakelight install question

I'm trying to get the running light feature enabled; so the LEDs will be on but not full intensity until brakes are pressed ( feature is built in). Its for the top one,or #1 in your diagram. The bulb harness that goes to this position only has 2 wires I think both black oddly. The unit comes with a plug that has just the red and black and plugs right into where the original single bulb did. So essentially the LED strip is now your light bulb. Then there is an orange wire coming from another location on the LED strip which it says to hook to rear running lamp( orange wire). The only running light in the rear of my car would be the LED taillight section n the quarter panel; which resembles the pic you posted except the wire colors on mine are black,purple,and orange. I just want to make sure that the orange wire that goes to the brake lights is definitely the one to be tapping into for this feature. Any thoughts?

Re: New LED brakelight install question

I just noticed you have a 2010. Is this the light in question?

If so, yes you would have to run the orange wire to where the tail lights are and tap into the running lights. I don't know the details regarding 2010 wiring though.

Either way, it's extremely unsafe to run a semi lit 3rd brake light if you're not actually braking and I would not recommend it.

Re: New LED brakelight install question

almost, its actually THIS one http://www.thespeedline.us/servlet/t...edan-4D/Detail
I dont see why you would say its UNsafe, in fact the reason I wanted that feature is FOR increased safety. Some jerk backed into my car while it was parked and claimed he didnt see it, luckily there wasnt any damage. This light should add more visibility to the rear end of the car. And the OEM tails have the same feature so I dont know why you would think this is different.

Re: New LED brakelight install question

If I had to guess, he's saying it's unsafe because a lot of people rely on seeing the third brake light light up when someone is braking; that's how they tell they are braking and don't just have their lights on. At least, I rely on the 3rd brake light a lot. Something that goes from off to on when the person in front of me is braking is much more attention-grabbing than just a light getting brighter.

Also, how would that increase visibility? It looks like your third brake light is about at the same level as your regular tail lights...
