Why wouldn't jeep make the entire lens a turn signal instead of just the small parts on the end?? I guess I get the whole led cool thing but the entire taillight blinking might've been safer since they didn't wanna do LED.

um, well, different resistor.

The 12V LED "bulbs" come with an internal SERIES current-limiting resistor (or other form of current source). But the LED bulb does not draw enough current to convince the "flasher" (in this case part of a computer somewhere) that the "bulb" is "good" .. so you need to add a SHUNT resistor to increase the current draw.

It has built in resistors to not throw burnt bulb codes on the CANBUS system. Don't forget that Daimler brought over the original CANBUS system when they were tied at the hip

Ha...learn something new everyday. Even as an engineer. Good thing automotive lighting wasn't my chosen path

Though, in thinking about that I can see why -- allows a broader range of compatibility without changing the current sense limits at the module.

"CANBUS" is a bit of a red herring in the LED bulb context. It is probably true that there is some minor correlation between vehicles that use the CAN bus, and vehicles that have a certain set of issues with LED bulbs.. but the CAN bus is Not a Bad Thing (if a bit screwy for us Ethernet types), and a 1998 Durango will grump about an LED bulb without resistors even though CAN is nowhere in sight.

CAN stands for Controller-Area Network, which is exactly what this mass of computers in a vehicle is. It started at Bosch, and probably got more traction in industrial control before it caught on in automotive applications.

Actually CAN bus systems are mandated in the US for all makes and models of passenger vehicles as of the 2008 model year -- at least as far as OBD II interfaces are concerned and those that must support them. While true that only the OBD interface must be CAN, every vehicle now basically uses CAN for its entire network (it would be ridiculous to translate CAN to another physical layer protocol just so that the OBD side was compliant).

I tried something similar to this and it didn't work, I would still get bulb out and hyper-flashing. I had to use resistors (see link below). My guess is that the resistance/current drop isn't enough when using the CANBUS bulbs.

edit: posted and then saw another post answering my question.
Anyone tried any of these Euro CAN-bus LED Bulbs in the JGC?

Re: LED tails...really?

I installed the VLED Triton kit and it is NOT plug and play for our jeep, only because there is nowhere to mount the control box. I had to splice wires and run them under the rear bumper and into the rear taillights because the control box's had to be mounted under the rear bumper . Not very difficult to do, just takes a little more time. I have had the kit installed close to three months now and it works great. Very good quality kit and the LED's are much brighter then the factory incandescent bulbs.

I have posted videos on the thread below. Just scroll down the page a bit. There's also a video of the Reverse LED's lights too.

Darn, can't seem to view the videos on my iPad.

Anyway, it looks like that VLED offers a 12" extension wire for the Gen2 V3 Triton bulbs. It is $4.99 a pair. I am not sure if 12" would be enough to get you to where you could mount the box or not.

Actually, the standard length is enough, problem is you can't even fit the connecter plugs through that small opening to tail lights. So that's why i had to splice the wire and pull it through. Those extensions are not needed and just won't fit to pass through.

Re: LED tails...really?

It's funny, my brother was using a 2013 Dodge Avenger rental and as I was following him, I noticed that it had LED tail, brake and turn lights. Not that is a major embarrasment to Jeep for being cheap and not installing full LED lights on their flagship vehicle.
