I just took delivery of the chrome LED tail lights for my 06 Lariat. The upper half of the light, where normally the red bulb plugs in is filled with leds and there is a battery(?) attached to these bulbs. The battery has 3m tape on one side so obviously it is meant to be stuck somewhere? As there are no instructions with these lights, my question for those who replaced their OEM tail lights is, where did you stick the led battery?

 

If you can, please post a picture of the lights. I replaced my taillights with LED ones, and I did not have any kind of battery to hook up. I'm not real sure what you are talking about.

 

This is a picture of the backside of the lights. Note the black plug at top (yellow arrow) is where normally a red/clear incandescent bulb would fit in the OEM lense. If these lights used the OEM bulbs the top bulb would plug in here. Instead, it appears you have to disconect a wiring plug from the OEM bulb fixture and plug it into this outlet (sorta like a trailer wiring plug). There are wires that run from the black insert/plug to the LEDs that fill the top half of the light.

Below this note the two wires that run to a black box with the red 3m tape on one side. This is what I assume is a battery or some part of the power source for the LEDs?

The white circle (noted by the blue arrow) is a whole where (again I'm assuming) the OEM back up light bulb simply plugs into place.

I've not removed the OEM light yet so I do't know what options are available to stick that battery? Posibly it can go right where it sits in the picture, but I won't know till I pull the OEM lense. Thought someone here might have had a similar experience.

 

That should be your "controller" (for the current lack of a better word).
It lets the LED blink at a normal rate. One of my boxes fell off (right-side) and the blinkers had issues maintain'g a consistent rate of flash after that period.

Also, I stuck the box just on the inside of the opening for the light (towards the back corner).

 

Thanks. That makes sense. I realized after posting the pic that the power clearly comes from the existing wiring that plugs into the outlet at top of the light. So I was beginning to assume the black box then was essentially an on/off switch or like a 'flasher' for turn signals. I guess I'll just find a place to mount it when I pull the OEM lenses and look for somewhere with enough clearance so the new lenses fit properly.

 

the thing with the tape is most likely a resistor
this will load the turn signal circuit so the flasher will work properly

 

Which vendors tail light kit did you use?

Thanks,
