Well, you have a wiring issue (unlikely if all you did was plug in to the oem harness) or (more likely given the discrepancies already noted with the seller and the product) piece of crap cheapo lights.....
My advice?
Pull 'em, chuck 'em and go buy something worth your money.
Also (and this is just my personal opinion) "halo/beemer" lights look dumb on these trucks. Not trying to offend anyone, just my personal opinion. If you like 'em that's cool, but I'm still gonna point and laugh with my brochacos as you drive by....
You must be registered for see images attach
And ill be zooming right past you flicking my attractive 'whistle call' at how cute you and all your brochachos are
Just kidding but back on topic:
No but it was an earlier investment i made on the truck back in 2011, didn't quite see where the build was going to go aesthetically as it was a truck and it was my main objective to get everything mechanically in tune and up to date.
I went from cracked taped lights to those, certainly an upgrade and i would take projectors over any fancy/aesthetically pleasing stock style headlight anyday.
As far as chucking these, i spent almost 100$ on these lights. visibility EXCEEDS SO MUCH over stock cruddy lights.
They look blank, they yellow in color over time. and im not a big fan of chrome housings as everyone and there mother has those.
I've never seen them on an obs before so i figured i'd give it a try. These projectors worked phenomenally specially compared to the stockers, at least while they worked.
however going back to stock or even fabricating a modded projector light housing isn't in my budget for this build. The goal is to FIX the issue or at least assess the problem whether fixable or not.
Projector lights were for my safety and visibility on/off road. i couldn't see a darn thing with my stockers even new bulbs didn't make a difference.
Projector lights with those 'halogen' bulbs was as close to 'halo/beemer' as i could get if your looking at it in that sense.
To each there own, but im more of a repair it if able to rather than toss more money out my a$$ kind of person.
I will get pictures of the back of the headlight housing and the connection of them, im 99% sure that they were connected to OEM wiring harness - i will take pictures after work.
The Halogen bulbs located in the link are the only lights that still work, it's the regular driving lights that aren't working anymore. I'll upload a video and show you in dash and outside view of what happens when i try to switch from hi to normal driving lights.
Aesthetically, they are what they are.
Functionally, Can they be fixed?
I haven't looked into the actual led unit in the light housing nor do i know which led bulb it takes, but its all encased so im unsure of how it can be repaired.
As said, i will upload pictures when im off work
appreciate all your responses very much, and am open to all advice and suggestions.
