March 1st update:
Having run them for a bit now, I'll add a few more observations:
1) I do see the flicker now more than initially. I notice it mostly at idle, and when I'm close to something that makes the hot spots more obvious. But no one I've asked to look for it notices it when I am driving behind them at night. Especially when I'm moving. I will eventually try a harness though.
2) The "reflective distance" (whatever the real term is; Hilldweller will know
) is significantly better than with the Deltas or the stock lights. I can see street signs or other reflective markers well beyond what appears to be the end of the effective light range. Not sure yet if I'll see animal eyes...
3) They do have a lot of "curb appeal" and I get asked about them a lot. Truck Lite should have sent me some business cards, like Shrockworks did when I bought their bumper, to hand out when people asked about it. To be fair, I get asked about the Vision X ones a lot too. And the ORH top. And, sadly, I got asked about the "cool blue" Deltas when I had them. But if you crave attention, these will get you some.
4) The gaps in coverage aren't the best on the highway. These really do seem to be better designed for a trail rig instead of a daily driver. I got out into a few fields just to see, and the hot/cold zone split is not really noticeable at all on more broken terrain, compared to what you see when it is projecting across an empty stretch of open road. I do want to see how well the aux lights fill in the gaps.
5) Snow and rain didn't have an adverse effect on performance. I know that the lights don't get as hot as stock lights, but so far I have not had any issues with accumulation while driving. Didn't get far up in the mountain passes yet to see what it's like in the worst conditions, but for normal weather conditions, these work great.
Overall, a week in, no regrets. I would agree with the general consensus that this are better designed for an offroad rig. Very durable, and light up trails great. But even on a daily driver, they are a very effective product. The Speaker lights seems better suited for everyday use, but the cost is skewed the wrong way for many. It's a D44 vs. a D60 argument for me - yes, you can spend more and get more. Just determine if you need to.
