I concur here. Without a proper aiming job they are junk. When done right they put amazing amounts of light in the right place. Fortunately aiming lights in these JK takes nothing more then a skinny T-15 driver.
I finally got them aimed halfway decent but the output to my is still really blocky, if that makes sense. Almost like an HID in a halogen reflector. The pattern is spread wide but its just spotty. I had to do a lot more than up down adjustments. First, the drivers side sat loose in the assembly and bounced around. Second, the head lights were cross eyed. There is decent overall output, but a funny shaped bright spot from each lamp that intersected in front of the jeep. I can't explain how obnoxious it was to watch the beams intersect and bounce around.
Anyway, once I finally got the lateral adjustments right it was much better. But the amount of light on low beams is still weak to me. I would like to aim the vertical part with the sharper cutoff, but you get the bright spots above that and they are really concentrated. The high beams looks amazing, I have zero complaints about them on high.
I do have the truck lite anti flicker harness, and I wonder if they produce a voltage drop to even out the signal. I may have to test them when I'm home next time.
I haven't seem the jw speaker head lights in action, but as I said I am very impressed with the fogs. Very wide pattern, full light, great cutoff. The two of them work well together but driving on a dark rainy night with just the truck lite head lights was awful. Well, it was awful with just the stock head lights on too.
Oh and currently I'm just flying Bell 407 and 206 offshore (gulf of Mexico). Flir would would be cool for weather but also for detecting flaring gas etc. We don't fly single engine offshore at night, but flir produces some amazing images in the dark, particularly in mountainous areas. Most operators just use night vision goggles for that now though.
