Factory Halogen to LED Headlight Conversion
My RR harness should arrive tomorrow. I tried the TRS harness but had issues with the passenger side park light coming on and staying on. Tried everything and got random results. I installed the RR harness on 11/21/16 and the passenger side park light will not stay on. It flickers as I move the switch from OFF to ON to AUTO. This happens when the truck is running. Turn signals don't work and I get hyper flash. The driver side works fine. I have a 2015 Lariat with DRL on and I run the halogen lights with the switch on AUTO. Hoping to do the same with th LEDs. With reading all the success and issues, I would like to know the following:
1.) Year and model truck?
2.) Which brand harness? RR, TRS, etc.?
3.) Success or issues?
4.) Do you have DRL and are they ON or OFF?
5.) Do you run the switch on AUTO?
6.) Do you manually turn the switch ON and leave them on? Or do you then switch to AUTO?
7.) Harness purchase date?
8.) Installed date?
9.) How long you been running?
I appreciate all the hard work/time people like Dawson has put into this effort. Just trying to see what's working and what could help others with solutions.

I'll start
1. 2016 F150 XLT Supercab
2. TRS(theretrofitsource) Harness
3. Success- Polarity reversed on turn signal for 7440 male adapter(I resolved my own issue)
4. DRL's are on(Canadian model)
5. Set up to AUTO
6. Always set to AUTO
7. Aug 23 1 2016, installed beginning of Oct 2016. Been over a month and a half now
Only issue I had in the beginning with the harness was the pin on the connectors where reversed and couldn't get the turns to work. Got that figured out on 2nd attempt of reinstall. I've had the odd led light out being out but to fix issue was flick switch to lights and back to auto and turns back on. Aside from that, harness has been working flawlessly. Overall happy with TRS harness

1. 2016 XLT
2. RR
3. Success
4. Work intermittent in auto..stopped using them...The LED headlamp has a separate led that lights up at a lower lumen on the stock trucks that come with led's ... lower trim simply lowers voltage to the DRL. That said you wont get true DRL from a lower trim until someone of knowledge makes a sensing relay to feed the led DRL a true 12vts when that voltage drops...just need to route that wire to the intended DRL.
Ill admit, I like the way the true oem DRLs look, that was one reason I bought the leds
5. No
6. Always manual..I dislike auto lights, every time I drive under a hwy they turn on/ off
2. RR

Not to Derail, but MF... I didnt know theyre were 2 leds in the low beam. 1 for low beam, 1 for drl.
Maybe thats why Ive saw alot of Lariats and above near me, with the low beams only, on during the daytime. Theyre bright for only being a seperate drl led...

I asked diode dynamics if they could make a sensing relay and tap this LED and they basically said no, not something they would do...I would buy another harness if they ever make it work!

1.) 2015 XLT supercab
2.) RR
3.) ISSUES - random turning off of driver side low beam. Unable to resolve with swapping harnesses, ballasts, etc... Headlight works fine driven off of 12V while bench testing. Stock halogen headlights and Anzo's work without issues. Still mind boggling and extremely frustrating.
4.) DRL Off
5.) Switch only, never auto
6.) Manual off and on as needed, no auto

1.) 2016 Lariat 501A
2.) Which brand harness? RR
3.) No issues that I have noticed. Knock on wood. I have diode dynamics switch back installed.
4.) Do you have DRL and are they ON or OFF? Run the on or off depending on mood.
5.) Do you run the switch on AUTO? Yes
6.) Do you manually turn the switch ON and leave them on? Or do you then switch to AUTO? Never touch the ****.
