JW Speaker just released a new headlight today called "8700 Evolution". Not too much information on it yet. FB page says you won't have to shave the headlight ring but you'll still need the H4-H13 harness.
The ring shaving issue is no big deal...it only takes a little bit of Dremel work and about 5 minutes time, so I'm not too sure why anyone would wait for the new model since the old one is so good, but whatever. More important is the flicker issue. It's not noticeable except at idle when using other accessories, but this is annoying and entirely a Jeep thing. Like the Cibies, you need to use a full harness, not the pigtail adapter, to get power direct from the battery. After installing the Rallylights harness, the flicker went away and lights are brighter. Do it once the right way and your done for the life of your Jeep. Money well spent!
