Signature LED headlights installed on Black Diamond - plug and play with no fault codes

[WeirdGuy]

Curious... What about just replacing the bulbs in the rear to LED? Since the front lights on ALL models are LED, then there shouldn't be any hyper-flash in the rear after bulbs are switched. Switching them to LED bulbs would at least give you a brighter and cleaner light look.

What's the process for swapping them out? How much disassembly do you have to do to get the headlights out?

I used this video.



It took about an hour all in with simple hand tools, not including the 30 minutes to run to the hardware store to get a Torx Plus 40 to remove the Brush Bar.

Hi all - there has been a lot of discussion about cross-compatibility, especially on the BD since the signature lights are not a factory option. I can confirm the Signature headlights can be swapped with the Standard headlights on the Black Diamond. The pin configuration is slightly different but they plug and play in the BD with full functionality and no fault codes.

YES. Basesquatch here I come.
how did you get them? Did you purchase directly from the dealer. And if so how much did it cost?

Did you have to re pin it?

I would suspect it will hyperflash with LED bulbs since the wiring between the two is different...however, I am going to have one of the guys at work check and see if hyperflash can be disabled like on the Super Duty.

No, it was a direct plug and play.

Thank you. Will definitely be interested in reading what you find out.

I’m doing this very thing. There’s one company that makes an LED bulb that is compatible. The bulb type is WT21 and is white on the stock unit. They actually sent me the WTY21 by mistake which only has two pins instead of four and would work for the backup lights if it were white (I ordered red before I knew the stock bulb was white.) I will likely replace the stock backup bulb as well at some point if I decide not to go with a pod or flush mount backup light because they don’t seem bright enough to me. The bulbs were shipped directly from the company and they are out of stock for another two weeks on the WT21.
I’m not sure why Ford is going with this proprietary bulb. Maybe someone can chime in and explain. I believe it was also used on some more recent F150s. It looks very much like a 3157 but supposedly is different in some way, possibly in dimensions.

You can also order them directly from the manufacturer.

Thanks! I will definitely be ordering these when my Bronco is finally delivered.

Tried. Results in hyperflash for the blinkers. Let me know if you know of a fix besides resistors

Bummer. I’ll see if I can figure something out. Thanks for the warning though.

Anyone know where the turn signal relay is located? I’m wondering if modifying the relay as outlined on this linked page would work in preventing hyperflash without needing the resistors.

My other thought is has anyone ever wired the stock incandescent bulb in parallel with the turn signal wiring just like a load resistor? This would run MUCH cooler than a load resistor and could be hidden in the area behind the turn/brake light housing.
