AZN Optics 5W5 Canbus LEDs
I suggest you place back your oem bulbs and send it in for warranty
Bottom line is the LEDs are a power consumption item and not a power generating item that would fry the harness in the rear that's not even that close the LED turn signal. They do bleed off some of the power through the resistors which do heat up as normal, but as that part is up and away on the opposite side of the bracket, the heat generated wouldn't melt something that far away and you'd see burn and scorch marks on the front of the bracket if that was the case.
I really dont think micheal is going to pay for the harness but i'm pointing out to all the people out there about to buy these that your playing with fire.. if you already have turnsignal leds... you better check your harnesses before it's too late.. dont get me wrong i love the look but weighing out looks vs a $400-600 bill i think i rather just have stock or the halogen super white..
Now you're just saying stuff and making assumptions. The LED components used by my manufacturer are 1210 SMD CREE LED Chips. There was plenty of R&D as well as clean room and live testing performed by volunteers and myself for w204s prior to release as those who've been on this forum long enough can attest to. There's QC that goes through by my manufacturer and also by myself prior to ship, I plug it into my power supply and measure.
You purchased those turn signals back in April and it's been 6 months with no issues, but like I said, it could be any number of things that caused this and you're the first to have reported any issues. These LEDs were designed and built to spec for our vehicles.

ok if ya say so... well then i just hope MB takes this back and covers it under warranty.. but honestly i've seen the xp-e and xr-e and xp-g cree's but i've seen fake crees look exactly like this on ali baba.. and they state cree but they replica them in china.. same thing with star pcb leds.. just the inconsistency is where the failure is and some heat up more then others.. for 4 years i played with leds for aquarium fixtures.. so i'm no stranger to leds...

all these are replica made leds... i know your chinese too as am i.. i know what we make over there and alot is fake or replica... any of these look familiar from above?? the wedge bulbs i can find millions of these suppliers of fake cree.. if these were true cree the cost would be definitely alot higher.. i pay per smd $3-4 at lot rate for true crees and thats buying 1000's of these.. at the price your selling em for theres no way their true cree.... any cree product is no less then $1 each.. that means that per led your putting 8+ leds on each.. thats $8 minimum per bulb and your offering $19 for both bulbs?? in otherwards their not true cree.. their fake imitation.. the $4.50 per bulb you can easily make a profit.. like i said i'm no beginner in leds.. I've been using them for aquarium applications for a long period of time..

Believe it or not, these are CREE SMD. You can get wholesale CREE components much cheaper than what you see on that link in mouser going straight to manufacturer and not buying through distributor. Just look up several legit competitors who also sell CREE LED components on amazon.com, sears.com, etc and you can see the prices aren't too far off.
Look, I'm sorry this didn't work out for you and it's obvious that there's no changing your mind on this, but it's a set voltage that comes in that the LED draws and burns off the extra energy in the form of heat at the resistor level which is far enough from the base connector and wiring harness that it couldn't have caused the melting. If anything, the LED itself would be scorched black with resistors separating. The feedback loop would at the most receive equal or less voltage coming in from the input and those wires can handle that by simply connecting a short circuit. 15 years engineering background with up to masters level education and 10+ years working in the engineering field for the DoD.

The temperature of the units at all operating voltages was not anywhere close to being dangerous for any plastics, wire, cloth, or even human skin. Some certainly got warm to the touch, but 30 degrees less than a fully operational filament bulb for the same application.
So even though we are competitors (friendly from my point of view), I would wholeheartedly endorse the products that we purchased from him in Summer of 2011. They worked well within design specifications, and were indeed CREE SMD.

)yeah, it would be illegal and not encouraging, but people will do what they want.
Not that I am encouraging him to drive the car like that.
