Re: Be careful with LED DRL's

I can't see what else would cause discoloration other than heat since the headlight is essentially sealed with the bulbs in place. I think your on the right track when you mentioned the fact that the higher powered Neutrons are directed right into the back of the reflector instead of dispersing the light into the full headlight housing. That has to create more heat than usual as all the energy is essentially trapped in behind there. Your also loosing a lot of the useable light output with this design I would think.

I think the neutrons probably melted that way, but Moose and I have the Nova 360 which I think could be a different problem. I was wondering if maybe as the electronics get hot for the first few times maybe some coatings, solder, or something is outgassing a little. I don't know at this point but I pulled mine out today until I know more.

Re: Be careful with LED DRL's

I dont know much yet, but so far I do know I am only the fourth set of neutrons to fail out of thousands, and no I do not know if the first three were melt downs or just diode failures. Hopefully know a little more monday, the engineer is looking into it.

Re: Be careful with LED DRL's

I installed a pair of these (http://www.amazon.com/gp/product/B00...ef=oss_product) this morning. Then we went out for lunch, 1/2 hour drive each way. Just checked then and there is already some "cloudy" discolouration above the DRL's. So needless to say they have been swapped back out to OE until this has been sorted.

The cloudness in the upper DRL's is put on in the factory, to prevent light "spray".
My led's are working fine so far (4 months now).
Sorry to hear about the problems, but bad bulbs or leds will always be there. Could be just bad luck.

Is that what the local service department told you, or was it confirmed/told to you by someone higher up at Chrysler?

I went past the local dealer this morning and the "demo" model they had did have the discoloration but there was a brand new one also on the lot with no sign of discoloration at all. It appears it may also only relate to the HID equipped vehicles DRL's as all the other Laredos on the lot and also the one I used to have had no discoloration whatsoever. I did have it in my new housings (HID) so I ended up cleaning it out there (if you try this be VERY carefull - too much pressure will wipe the chrome right off the reflector)

I'm 95% convinced it did not come like this from the factory.

So does that mean you also have the "cloudiness" above your DRL's?

if so, Has it changed at all since the install of the LED's?

Re: Be careful with LED DRL's

Could any of the issues be caused by loose/inadequate electrical connections between the bulb and socket or somewhere else in the bulb itself? I think the heat discoloration would point you in the right direction to look and I don't know what a brand new bulb looks like, but that would be good to have for comparison.

These custom made LEDs have a transistor that is built into the circuit. Anybody familiar with electronics know that transistor get VERY VERY HOT.

I do know that V-LEDS attach heat sinks to the transistor in their LED circuits to dispense the heat as best as possible.

Notice the metal ring on these 3157 LEDs from V-LEDS. It's not there for eye candy. It's a heat sink.

Re: Be careful with LED DRL's

As you can see in this picture, the circuit burnt up. NOT the LEDs.

I'm not sure if the shiny part of the Pucto fixture is metal or not. And if it is, what's it for heat sink purposes....
