Very nice writeup. I've been goofing around with LED'S now for years and years, in all kinds of small projects etc. Over on one of the Jeep forums, the subject of LED headlights has gone on for YEARS. Jeep, in it's infinite wisdom, didn't actually change to an LED headlight 'till the model year '17. And that was for the Rubicons and the Sahara models only. You could opt them in, on lesser models but, it was very costly. I have the '17 versions on my '15 Jeep JKUR and, they, without a doubt, are a far better light than the junk Halogens originally supplied.
But, I've been thinking about doing an LED headlight swap in the TW and, your writeup is GREAT TIMING! A great buddy of mine I worked with on the SDFD, Jimmy C, otherwise known as "Jimbo C" (noted for his wind shields he makes for the TW), has what appears to be TWO LED headlights in his. I gotta ask him about his and see what he thinks. But, I like your analysis of that product. Thanks a heap.
