4x4² carbon visor LED light activation harness

Here is the wiring kit to turn on the LED lights in the carbon visor on the US model 4x4².

I currently have this one only, more on the way.

The way you did it is a little dangerous, my kit connects into the CAN to correctly control the lights. Also comes with an upgraded antenna.

Not dangerous at all. Simple electrical connection. Your way costs an arm and a leg and has many more parts. How do you think the 2 front leds are connected. Or all the Orange marker lights. They don't each run off their own system. The lights are all wired together.

When I was in Germany last month and met with the engineers at LeTech and discussed the "jumper wire" method of activating the lights they said "it is a little dangerous" and the CORRECT way to do it is to install a complete separate harness for these LED's along with a relay that connects to the CAN system.

Hey, it is not for everyone! But for the 4x4² owner that wants to do it the proper way and can afford to do it, this is the kit to go with.

I understand you're in the business of selling stuff and that's fine. But to come on a forum and call it dangerous to add 2 led lights onto a set of other led lights lowers your credibility as someone who works on these vehicles.

Most people understand that an led light draws much less current than does a standard light bulb. The led lights are driven by a 5v light driver. The 2 front led lights by the headlights are connected together. When branching off them to add 2 more led lights, the current draw is minimal and voltage drop is about .2 volts which I tested.

We are not talking about branching off the power running to the timing sensor of the engine to create something "dangerous". You're talking about simple electrical wiring and at the absolute worst case if it was "dangerous" the "danger" would be blowing a fuse or damage to an led light.

The same guys at LeTech and Brabus told me I shouldn't put 37" tires on my car (as I was one of the first in the US to get a 4x4 and change my tires) because the axles weren't designed for it even though Mercedes and You are selling 18" beadlock wheels to be used with 37" tires.

Also, the Mercedes Benz dealer in Atlanta will activate your upper LED lights using the same exact method and harness as I have. They will warranty the work as well. Anyone can take their truck to them and have the upper LEDS activated and the way they do it is the "dangerous" method I chose.

To to date I have more than 12k miles on my car with my "dangerous" led lights and 37" tires my axles weren't made for. I think life will be ok.

FYI, we purchased Bill's Adaptors, and are having the Dealer install.

When it comes to "accessorizing" a $240k vehicle, cost is generally not an issue.

CrazyMD, you are definitely one of the few who decide to do the work themselves, and your work is astonishing to say the least.

The majority of owners who can afford this truck definitely won't be trying to tackle projects like these on their own, so we are happy to pay the premium for a product done right, and then pay professionals to install said product.

To each their own, let's keep driving.

Right, but to have Bills kit installed on your vehicle its likely your headliner and carbon fiber light bar needs to be removed. Thats hours of labor and likely things don't always go together the same without a broken clip here or there.

The kit Im using doesn't require any disassembly of the vehicle other than simple removal of the headlight and the OCP/sunroof switch panel to be lowered.

I prefer not having the dealer or whoever else drop my headliner to activate 2 LED lights. Im all about simplicity. But yes there are always multiple roads to a destination. I just prefer the simplest and easiest road.

Correct, however I get mine directly from LeTech / Brabus in Germany, I refuse to believe German Tuning Company a Brabus distributor in the USA gives a "deal" on anything.

Would be interested to know what they are charging.

I just got 8 kits in, sold 5 right away, still have one standard kit and two with black lamps.

Drilling the roof? No way.

Just found a way to run the cables through the A-Pillar. I just installed a 50" single led bar in my roof rack and i run the cables through the A-Pillar directly to the positive and negative harness in the engine bay. Mine is a 2008 G320 CDI.
