Flickering Switchback DRL's w/ Triton V6's

[LipschitzWrath]

Have any of you guys experienced this? I purchased the switchback DRL's from Daytime Bright Lites for my 2014 Taurus SHO on which I had already installed the Triton V6 switchbacks (w/ 6Ω load resistors) from VLED's. Upon installing the DRL's, I noticed that whenever the amber is activated (t/s, hazards, lock/unlock) with the engine running, the amber flickers/strobes. I immediately contacted Dan at Daytime Bright Lites and he told me this has happened before and was due to a bad batch of controllers. After the new batch came in, he sent me one. Same result. Here's other information:

• This ONLY happens when the engine is running. When the engine is off, the DRL's function normally (no flicker/strobe)
• The fuse tap was moved to a different fuse slot - no change
• Dan sent me 2nd new controller and even 2 new DRL's - no change
• I purchased a set of 3Ω load resistors for the Tritons and installed them - no change
• Dan sent me a 3rd new controller - no change
• The courtesy light adapter was bypassed - no change

Has anybody got these two pieces to coexist peacefully? Experienced this problem? I PM'd SHOdded since his sig notes that he has them but he didn't reply. I also don't know if this is unique to the V6 Tritons. Maybe this wouldn't happen with the old V3's?

Dan is all out of suggestions and I don't blame him. Given the number of replacement parts he's sent me, I'm thinking that one of his parts being faulty can be safely ruled out.

Can anybody help me?

This exact thing happened on my 2015 with iBrightstar switchbacks from Amazon. I contacted the seller and they sent me a replacement set for free but still had the flickering issue. I then ordered a different set from Amazon and they worked flawlessly. I was thinking it had to do with any voltage above a static 12v when the engine was on (approx 14v). Someone on a Facebook group mentioned that the BCM used PWM on all bulbs to help them last longer. Regardless, the replacement ones didn't hav e the flickering issue. I did not use resistors and only disabled bulb outage notification on all lights using Forscan. FWIW, these are the switchbacks that I used:

Been through this. See --> https://shoforum.com/index.php?threads/drive-brights-flickering-again.139370/ Thankfully mine is still working normally. I have LED turn signals working ok with them (not switchbacks). I wouldn't think the problem is related to the switchbacks.

I agree, the switchbacks are unrelated in my opinion. There are others with this problem running the stock turn bulbs so I'm thinking that's a red herring.

Thanks for the thread. It looks like I'm not the first to suggest a voltage regulator, but I didn't see anyone who's actually tried it?

If you saw my thread over at EBPF, I have a voltage regulator on order that will be here Thursday. I'll adjust it for 12.5V with a 14.4V battery voltage and hope for the best.

Maybe it won't work but I'm one of those people that has to *** on the electric fence for myself.

No, I did not try a regulator. I did try a few resistors & caps (don't remember the values of the components I tried) on the + side to the DRL controller but the flickering persisted (w/ engine running).
Please update this thread with your findings once you try the regulator. Good luck.

My conclusion was that it was an LED issue with the brand of switchbacks I used (iBrightstar) not performing as expected when voltage was greater than about 12V. The amber side of the switchbacks would only flicker when the engine was running and not flicker when running off battery voltage when the engine was off. Since changing to a different brand, there have been no flickering issues.

I think the problem is the same. Our solution is not. In my case, it's my DRL's that are flickering. There are not alternative suppliers in this case.

Guys, I found a solution to the problem. I am refining the solution to something even cheaper and easier. Rather than repeating it here, my post can be found on post #15 of this thread:

Excellent! Thanks for the update. I look forward to the refinement. I should have 2 or 3 spare controllers that will work w/out the annoying flickering once you confirm the resistor values.
