Why is it okay to put LED's in everything else? Tail lights, etc are on for long periods of time and have no problems. I think the issue with my situation is its a neutron bulb, not a nova bulb, and the concentration of light is at the tip, which means it was reflecting a lot back due to the jeep "grille" (aka diffused) in the DRL housing. LED's run cooler then incandescent bulbs, so heat technically shouldn't be an issue, but as you can see heat and/or failure of the bulbs was evident in this case. Many people run LED DRL without this issue, so I don't think its necessarily not OK to run LED DRL.

I don't know....and it SUCKS... Sorry about your lights. I would think one of our vendors on here, who knows this info, could tell us. I don't know jack about bulbs, but I do know I read on a few sites not to put them in the DRLs specifically......and I did stay Holiday Inn Express last night

Re: Be careful with LED DRL's

Something is strange if both you and Moose are seeing discoloration inside the housing. Definitly heat related but as Mr12Volt noted odd since LEDs are supposed to be cooler than the halogens. The first set I had I got off ebay and I did not notice any discoloration, and the second set I picked up locally and have been installed for a few weeks now with no apparent issues so far. Going to be keeping a very close eye on them now. I also just upgraded all the other ext lights to LED - Hope the whole damn jeep doesnt melt down

No offense, but that is stupid. Why wait? Most of the online retailers specifically tell you NOT TO PUT THEM IN DRLs. 2 people here had an issue, and you want to wait to see if yours will be OK?

Really???
Take them out of your DRLs, if you wait, don't expect any sympathy when yours fry your lights too.

These cars are too pretty to think " Maybe it won't happen to me"

Re: Be careful with LED DRL's

Despite this serious heat issue Jorde experienced, and despite slight brown discoloration on a portion of my sockets (only a anal retentive person would have noticed - me), my DRL LED's and countless others are working fine. All the major LED manufacturers have bulbs specifically intended for DRL run times.

That said, I'm not about to give up my LED DRL's cause they work nicely. The rest of my tailgate and interior LED's are great upgrades, and I'd like to find a punch up for the fogs as well. We have also run LED's on a boat and love them for their lower heat, lower energy consumption, and better lighting.

My only real complaint is that they are expensive and the restocking fee is a bit ridiculous. That said, you get a lifetime warrantee and replacement for the price.

Soooo, I do agree we need to pay attention and figure this out. I'm sure Jorde will have some kind of response from Putco. It could be a simple manufacturing issue, the wrong bulb, or something else.

Re: Be careful with LED DRL's

FlyFlip420: So because 2 people out of probably hundreds had issues that means all LED's are bad? The shop where I bought them said if you were not seeing flickering etc immediatly after install that they should hold up just fine. If anything it seems the Putco brand is the issue and not LED's in general.

I ran my first set of LED's that I had (not putco's) in our first WK2 for just under a year with not even a sign of discoloration and the new set appears to be working just fine with no ill effects at all after a few weeks.

Moose: I picked up a set of LED's for the fogs and they look MUCH better than the halogens but definitly have more blue coloring than the stock HID's. I was hoping it was going to be a closer match so I could run them all the time but that may have to wait until I replace the factory HID with either 5 or 6000k bulbs. They run MUCH cooler than the stockers - after only 2 min the stock bulbs made the fog light lense quite warm to the touch while the LED's had no heat coming off them at all.

Re: Be careful with LED DRL's

It could also be the type of LED that is the problem. I believe the putco's use the larger high power LED's while the ones I have use a larger amount of small LED's

Actually after a close look at the melted pics above they look nothing like the ones I have. Mine are the tower style (the LED stack is about 1" long) and has LEDS on all sides and the top, not just out the front.

Agreed, and Jorde is checking this out.

Looks like the DRL LEDs that melted are the Putco 7440 Neutron, billed as the brightest LEDs. Note: I and others use have successfully used these as reverse lights in the tailgate for both brightness and the lack of need for a 360 degree bulb back there. Note the T-shaped unidirectional bias.

http://www.putco.com/products.cfm?ac...5-b085cb11ab2b

The tower shaped 360 degree bulb that I and others have used successfully for DRL's is the below Putco 3157 Nova 360. Like 604, mine are going on 12 months now.

http://www.putco.com/products.cfm?ac...7-c567591c3925

Like 2for3, others are happy with the Vleds for DRL's, as follows. Maybe HemipowerV8 can chime in. Note these are the one's that Vled notes should not be used for DRL.

V-LEDS 5k DRL Replacement

Vled however does have a set of LED's in the 3157 model that do show appropriate use as DRL.

Thanks for staying on top of this, Moose. I like my white DRLs but don't want to risk a melt down!

I think (just postulating) that the problem may stem from the more intense LEDs in the Neutrons being concentrated at the tip - generating more heat than other LEDs but also all the heat is getting reflected right back at it. Or it could be a manufacturing issue too.

At lunch after a 10 min drive I jumped out and used an IR thermometer on my DRLs and it was just above ambient. If melting was imminent I should have seen 100F+. It is a little tough to get a good reading though since the DRLs go out when you put the parking brake on or put the truck in "Park", but I'll try to get a reading with someone holding the brake soon.

Re: Be careful with LED DRL's

^Thanks Brandon, but ironically, Jorde is really the guy who deserves thanks.

Not only was he the first-mover guinea pig and was exposed to this because of it, but he made the effort to write up the correct WK2 LED bulb list for our collective benefits:

I also have the Nova 360s for DRLs and today I noticed some slight cloudiness on the reflector above them. I am not convinced that it is a heat problem, but I am going back to stock today. Maybe I can find a whiter non-led bulb in the future but for now I'd rather have the yellow tint bulb than to scar my reflectors brown. Oh well.

Edit: As noted further down in the thread, the cloudiness is apparently present from the factory or at least present in non-modified Jeeps with the HID / DRL combos.
