Had LED headlights installed and now headlights ( low beam only) will go out whether or not the the headlight switch is on auto or the on position. Any ideas what this could be? Truck is a 2015 Ram Big Horn.

Canbus?There is something with the '15 model year that makes them more particular about the lighting. I bet the headlights work fine when the ignition is on without engine running.
Aside from using "Canvas read" LEDs, you might have to use AlfaOBD to change the headlight type to LED. Another thing to try would be using resistors.

dam spell check..lolCanbus?
dam spell check..lol
yes CANbus
@RamDiver I'm blaming spell check.
There is something with '15 model year trucks, there are some parts that are year specific.
I think Warlock only came with Projector housings, in Chrome or Black.I'm curious about the '15 model year trucks. Do they also have different options for light housing types and do you know if one is more problematic than the other?
I've learned that my Warlock has 3 potential light housing styles. Now, I have an extra set of Fahren H11 LED bulbs.

"spell check" yer friend, roflmao. I hate it EVEN more on I Phone. Sometimes, I just turn dat junkola off.dam spell check..lol

Aside from canvas read I agree with this. I was installing a wireless backup cam so I tapped into reverse lamps so that camera came on in reverse. Worked with key turned on, but as soon as I started my truck wouldn't work. Took me a while to figure out,but when truck is running it doesn't supply a clean 12v to lights which was necessary for the camera. I ended up tapping reverse from trailer harness which is a constant 12v when active. I've had zero issues with LEDs (led fog, lows, reverse, cargo and all interior),but I did look for ones that were supposed to be canbus friendly. Now I have alfaobd so shouldn't be a problem even if they aren't canbus friendly.There is something with the '15 model year that makes them more particular about the lighting.

Really? How so? Quite a few people run them with no issues.LED headlights will mess up your TIPM.
Hmm... I guess the tipm in my last Ram missed the memo on that....LED headlights will mess up your TIPM. You can get it rebuilt for about $200 if it isn't fried too much. A replacement is around $1500 for a rebuilt one.
I bought a 2006 Ram 1500 5.7 two years ago. Headlights only worked on high beam. One of the first things i did was replace both headlight assembly's; same issue. After a couple of weeks working on it I called the previous owner; he 'fessed up that he'd tried to put led headlights on and that was when everything quit working.Hmm... I guess the tipm in my last Ram missed the memo on that....
It won't damage the TIPM because you're not introducing more load to that circuit. You're actually introducing about 60-80% less load on that particular circuit. The only downfall has already been discussed. Your canbus system (think computer) may not recognize certain LEDs and will be expecting more resistance from the circuit than the LED provides. To solve that you either choose a canbus friendly light or install resistors.
LED headlights frying the TIPM is a well known Dodge issue. If yours quit working when you put the LEDs in try putting the originals back. If the originals work, you don't have a TIPM issue, but if they don't you've got a TIPM problem.Really? How so? Quite a few people run them with no issues.

I sent the TIPM off and got it rebuilt, headlights started working again. TIPM issues when "upgrading" to led headlights are a well known issue with Dodges. "Load" isn't the only problem; the circuit boards in the TIPM control the headlights totally - no fuses or relays. Dodge TIPMs are very sensitive and easy to fry.
Agree, 4th and 5th gens are designed for both halogen and led which is why we can easily switch with alfaobd now. I never even set mine for led and have zero issues even with upgrades EVIC which is known to be more sensitive to led bulb out errors.You will have to do better than that dude.
There are many users besides me who have successfully installed aftermarket LED headlights.
And where did you get the idea about no fuses or relays?

I'd call that a coincidence... I'd bet my paycheck that LED lights absolutely didn't fry the TIPM.I bought a 2006 Ram 1500 5.7 two years ago. Headlights only worked on high beam.
