Very complete & helpful review, thanks! It answered all of my questions except one: what's the latest & greatest in (what was, oh, a month ago) the debate about pulsation & the need for a direct-to-power replacement wiring harness (not just connector adapter cables) with the newest model lights? Personally, I'm most interested in results with the 2012 JKs if that info is available. Feel free to point me to another thread & say RTFM. Thanks!

 

I have them in my 2012. I used the rallly lights harness which gives full power and prevents any pulsating. Search and you will find all the information you need and then some.

 

Will do, thanks!
