Default LED headlight "conversion" on T1N

I've searched to see if anyone's used these new fangled things, and haven't found much.

The fact that they seem a bit new fangled gives me pause, but the general public review of them seems positive, though I can't find an instance of anyone using them on a T1N. Specifically, the Cougar Motor LED conversion kit:

https://www.amazon.com/gp/product/B0...k_ql_qh_dp_hza

I'll find out soon enough in real life anyway as they'll be here tomorrow, the price is sure nice, and my only real concerns are:

-will the plastic headlight cover fit back on?
-will it trip any codes?

I'll report my findings back here. I'll take any extra light I can get, I live in a place with dark windy roads full of deer. I have a 30something inch LED light bar slaved to my highs which is incredibly successful when the highs are on, but the lows are still kinds pitiful, and yes I keep my lenses cleaned and do the occasional repair service on them.

Until tomorrow, anyone have experience with these bulls or similar?

I put those in my friends 98 dodge 3500. They were ok. I think hids may give more light still.

He liked the led since he still had drl, low, hi. In one bulb

Thanks for the replies, I installed them yesterday and have my first impressions.

-The light is most certainly whiter than a standard halogen bulb, to be expected. They're 6000K, and I've always been skeptical about the light from this Kelvin range for anything. For Indoor lighting I don't like anything whiter than about 3000K, and while these are headlights and not interior lights, I'm not completely sold on the color. I think I can get used to it, and I do think the light is definitely more even.

-The price is nice, like $45 with tax or so which is about what new high quality halogens cost, and I go through about a pair of those per year. They claim a 50,000 hr life which is pretty impressive.

-I didn't think the headlight covers would fit back on because of the extra bulk but they do!

-with my brights on which are still halogen bulbs, and my 32" LED light bar this thing can really see ahead on the road now! I'm extra careful with my brights because of the light bar, but I also have much better visibility for those rogue deer that are always right there on the side of the road.

-the light cast to the sides is more even and more illuminating.

-no error codes thrown

I'll get some pics of the difference in light with my good camera soon...

I have a set of those same lights that I'm about to test out. I felt that they needed to breathe and be allowed to cool down, so putting the plastic cover on the back without drilling some venting holes was a concern to me. Id like to hear how yours are doing
Also, if they were causing any problems, they would blow a fuse or something, not throw a check engine light.

I mentioned no codes because it seems to be a (solvable) issue with some vehicles, though probably more with newer ones.

I had the same thought about heat build up and some ventilation. I was thinking of either just drilling some holes towards the bottom where water would be less likely to intrude, or maybe gluing a little eyebrow kinda thing above where the bulb is and adding the ventilation there. Wouldn't be hard, just a little piece of plastic and some q-bond or some such.

The lights are growing on me I think.

I am not a fan of the 6k light output, color rendition is pretty "wrong" with 6k lighting. I really wish they made 4k versions of these, much better color rendition, thus a better chance of seeing deer/moose/etc.... I have stock headlights, but with all the wild life around here (Deer Elk Moose) I do long for something better...

100-300w LED lightbar slaved by relay to the brights. Technically illegal in some states, but absolutely game changing.

What he said. Right up there with a GDE tune imo...
