I'm curious about the flickering that some members have reported with LED headlight bulbs..about how long did it take before this started happening ?
As I mentioned, my el-cheapo LED mirror lights started flickering about 4 months after installing them. On that note, I only paid 14 bucks for 14 lights. I haven't had the headlights in long enough to have any flicker issues yet.
As for light scatter/cut-off of LED vs the halogens they replaced. If you look at the picture that I posted of the 2 lights beaming on my wall in the garage, they project a similar spot on the wall. The LED bulbs I bought have 3 LEDs on the top, and none on the bottom side( so they don't reflect upward blinding people while scattering the light up into the air ). 2 LEDs run in low beam, and 3 for high.
My nighttime visibility is significantly better than with the halogens they replaced. Low beam was barely OK with halogens, and high beam flat-out sucked, therefore I used low beam instead of high beam on the highway.
I will say, it did take quite a bit of aiming to get it right( well very close, I may tweak the P.side light a tad more ). At first, the low beam was quite awesome, but I couldn't notice much difference in high beam, but it was better than stock.
At first I trial and error-ed it because the information I was finding on adjusting headlights wasn't very clear. This went on for a week-go ahead and laugh:grin -, I couldn't seem to find the sweet spot, it was better but something was still off.
I figured I would keep asking my buddy, Google, until I finally found something I could understand, and roughly followed the guidelines because I was pressed for time. FFW>I'm quite happy now, and would likely not consider using halogens again. High/Low are much better than the stock bulbs, and the clarity is similar to HID..it's as close as it get to and HID projector retrofit for my FJ( I intend on doing an HID projector retrofit for mine at some point if I can figure out how to do it all )
I can try and get nightspots, but the light output always looks subdued with my iPhone cam when I tried before. Again, for a plug-n-play fanless, box-less LED headlight bulb for 45 buck..about what some are paying for 2 halogens..they are hard to beat, even if they only last as long as a halogen, the light they cast is so much easier on the eyes and so clear that it's worth it to me.
