Great 
. Your workmanship better than me. 
Clean and tidy.
I found 1N4004 may die due to 1A current rating only. Better change to use 1N5408 for large current rating.

My Ride: 04' 545i, Sport Package, Black, Active Xenon, ARS, Aux Input
'10 Tahoe, Black on Black, leather, Nav/XM, 20" tires, full body kit, power 2nd row, loaded
'93 Jeep Wrangler, lifted 4.5", 33" meats, Rampage Recovery Bumper w/Tire Swing, etc
25' Aquasport Osprey, Center Console,2012 200 HO Etec
What would the cost be and how easy on a DIY install?? I am mechanically competent and do most of my own mods and work on my Jeep project but not necessarily electronically competent. If the price is right and install isnt too labor intensive I am interested.

Help!
Doing this diy myself . Currently have circuit board built but can't get turn LEDs to work maybe I have MOSFET connected wrong . Not sure of pins or maybe capacitor, is this polarity sensitive.
Also my fog and two bulbs behind rods are also on.
Anyone

good job Ricky , my advise in this retrofit : if you take a V12 signal from the number plate light , then your Tailights bars will always be as bright as the OEM LCI all the time ,, not only when you brake
I've done mine 2 years ago , I've taken the brake signal from the third brake light , I found the wires under the rear seat ,
