I installed an ARE Series cap a month or so ago on my 2011 FX4. I was impressed with the cap, but the one thing that lacked was the pathetic 12v light they put in there. Im still amazed with the technology out today that a company would still install these anemic pieces of crap in such a nice product. All to save a dollar I imagine.
Anyways, I knew I wanted better light and that LED's were the way to go. I did some research and found the product I needed. I ended up getting 3 LED light bars, (1) 12" and (2) 24" LED light bars. The 12" is mounted above the rear lift gate window and the 24's are above either side window.
I used these found on superbrightleds.com:
I was super impressed with the quality and light output. Weather proof and no need for resistors, ready to be wired in. A great product. I used the clips that are availabe to purchase to mount the lights to the cap. I simply removed and reinstalled the screws holding the window in place.
I did my best to keep the install clean and neat. I weatherproofed all the connections and hid the wiring as best I could. The switch is always hot so I can have power with the key off. All said and done I have around $100 in this including the lights and some misc. parts (wire loom, wire, etc).
Any comments and critique are welcome, be happy to answer any questions as well.
