I've always felt that my 2014 Lexus IS350 F-Sport did a bad job of illuminating the road ahead but ignored it assuming that it was more due to the car's low ride height than anything else.

correct light alignment is a riddle for me. I think that most likely it is an regulatory/legal issue..
In my jurisdiction xenon lights need to have automatic alignment, I don't know how exact that thing is
In the newspapers I read that the manufacturers want to introduce some laser-powered headlights. That things are so powerful that the regulation agencies want some "automatic recognition" of other vehicles in order to not dazzle them, I wonder if/how those get introduced
> Vehicles with xenon lamps are equipped with automatic headlamp range control. As a result, the highway is always optimally lighted, regardless of load conditions, and drivers in on- coming traffic are not blinded.
@Zaid - Not yet. I figured out my coils aren't getting any power, which is a huge thing. I need to figure out where they should be getting their power from exactly and why it isn't getting there. That could ultimately be the smoking gun.
I've seen two different diagrams (both from Subaru). One says they should be getting power from the ECU. Another one says they should be getting direct battery power (it even shows it as being fused, but not switched).
@BobCross deep voice Answer me, o dark one: How does a vehicle can recognize incoming traffic, what mysterious, unholy algorithms are needed to tell moving headlights from other light sources. drags various specimen of livestock to the sacrificial altar
@Myself - I found out it wasn't a fried ECU is what I found out.
It was a bad assumption on my part. Now I have a spare ECU.
The connection which energizes the fuel pump wasn't a good one. It's very intermittent in fact, which will be problematic going forward.
There are a couple of different connections which can cause the fuel pump not to energize at key on. I've got to figure out where exactly it's at. I thought I had it figured out, but I was wrong. Great fun.
Not at this point. It's all short and read the blinks. I don't even have a CEL hooked up off of the ECU. If you see above, you'll see I am not getting power to the coils. I'm hoping once I get that figured out (the correct way ... I could always jump them), I may be a lot closer to solving the issue.
As far as I can tell, the injectors aren't firing either (not getting wet spark plugs), so that may be an issue. The injectors do have power to them.
@Myself - They still could be, but without power, nothing's happening. I figured out how I could measure the power to the coils last night and it read ~.5vdc with key on. I don't know where it's getting that power from, but it isn't right, that's for sure. Should be full battery voltage.
@Pᴀᴜʟsᴛᴇʀ2 IMHO: Either the supply wire is incorrectly wired, current gets drawn away (short somewhere, clamp meter would be helpful) or the supply connection is faulty?
@Myself if I had the ability to start from scratch, I would put transponders in all vehicles with an array of receivers on the top of the windshield to allow me to do beamforming. Ping the transponders in vehicles around you and get a range and bearing on all of them.
Or I'd use a higher than visually obvious cycle rate for the LED / laser headlights that was only used for vehicles. It would have to be higher than 100 Hz but you'd know that that light is from a vehicle, not a streetlight.
If you really wanted to use only computer vision, I'd go with the image of the cockpit and the monkey who's texting behind the wheel. :-p
Those people would get a pulse of my laser headlights at 1000% normal brightness.
@BobCross And if I would like to analyze a recording of a camera? Search for bright spots, calculate the position/movement, subtract my movement from their movement and see if their position is stable?
For that recording, do you have all your own vehicle telemetry recorded and time stamped? How about video: how many cameras are you using? Multipoint parallax really does help with dynamic ranging.
The targeting solution is simplified since your laser headlights are a speed of light weapon system ... or were you trying to avoid the enemy cars? ;-)
If you mounted cameras at the upper corners of your windshield, it wouldn't be hard to do some spectral analysis of some of those headlights. Halogen, laser and LED bulbs have distinctive spectra, right?
Then the trick is identifying that this light in this camera is the same as this light in that camera. Trig ensues.
@Myself self driving cars will greatly simplify a lot of problems. If nothing else, it will give the texting drivers a safe place to text while not really driving.
The autonomous vehicles will also be using plenty of active sensors. It's a lot easier to localize something that's constantly saying here I am!
Also remember that you have visual cues from the road. If lights are moving parallel to the road lines, there's a good chance they're a vehicle. If they aren't moving parallel, turn the lights way up because something bad is happening and the driver needs to see
@Pᴀᴜʟsᴛᴇʀ2 here's an idea. Remember those two wiring diagrams you shared?
Could you go through and verify the readings you get for each connector/terminal with both ignition On and Off, for wherever you have values reported in the tables?
Sorry, I said diagrams a few lines up when I meant to say tables
The idea is to see if you find any pattern between discrepancies. It should help you see if the issue is related to a certain terminal, connector or bunch of connectors

@Borodin this answer isn't about giving the OP a fish, it's about teaching them how to fish. They thought that map would help and I wanted to walk them through why it may not be the magic bullet they think/thought it is/was. The "I'm not so sure..." comment follows through on this train of thought, which is why it appears at the end as a conclusion. — Zaid17 mins ago

@Zaid my very most favorite thing to do with those guys is to make it explicit. "I know it's important to you to have the last word. I wish you joy in the last word." ;-)
@anonymous2 - It's what they were saying in the Teacher's Lounge ... I believe I've read it in a post somewhere, too. SE is getting away from hosting/providing/linking the blogs. If a particular SE wants to host their own, no issue ... but it's on the SE to do all of those things.
@Zaid - I hear yah here. I've already gone through and checked, but other than obvious things, I didn't find commonality as you're suggesting. I've got a track of some things which I'm going to follow tonight and see if it is fruitful. I think I may have some stuff wired wrong.
The Subie is being a pain, but I think I might have a cure. The real pain is, I think I wired it wrong from the get-go.
I'm going to have to pull the wiring harness back out and rework some areas of it. I think the "instructions" I read were not very clear and I miswired some stuff. I don't have any power going to the coils because of it.
For those who care, there's only 1.043M seconds until WINTERBASH 2016! Woot!
@Zaid - I'm actually a fan of the injected. Being a nerd (or geek or whatever I am), the computer aspect of it is where it's at. I love the fact you can idle fuel injection in the cold without having to worry about a choke or pumping the heck out of the carb to get it going. I will almost ALWAYS move towards FI over carb. No competition in my book.
I've just got to put this stupid wiring harness back together correctly so it will run. I don't think it will be that hard, but now that I've been paying closer attention to the wiring diagrams and less attention to a set of directions, I think I might have a handle on the issue.
I don't think I told you. About 3 weeks after i started this mess, I found a replacement engine (same-same as what comes in the car) for $450 ... I was like ... ARGH!!!
I'm too far along with it (too much into it; too much out of it) to just get the EJ22 and call it a day. I'd probably have to get a bunch of parts to make it work.
@Zaid - I don't know that it's "better" ... it would have been far easier, though ... and cheaper!
