Laser Rolls-Royce headlight Circuit- Power/canbus identification help needed

Hello i have a very special headlight its a laser headlight from a 2022 RR.   

The car was in an accident and I managed to salvage a headlight my plan is if I can get this headlight to work I want to retrofit it onto my motorcycle the only problem is that I was confident in my ability to figure this out until I found out that it was not an LED headlight but the laser headlight and any experience I've had with lasers is I just break them so I'd like to reach out to some more intelligent people than me that might have some insight on the topic of lasers and circuits and repair.

I will provide photos of the entire headlight and all of its parts but there's the main beam which is laser that is what I'm trying to figure out but it also has additional LEDs.

I have a microscope i am Attempting to take photos With As its not Actually setup with a camera meant for it so hopefully i get some better shots of the circuit.   

First time posting this seems like the most active electronic repair forum out there You Guys are really flying under the radar

So I've got all the other LED lights working and based on the wiring I believe that the first pin starting from the left would be either positive or negative and then the third pin would also either be positive or negative if I didn't end up cutting the freaking harness to get the LEDs working I'd probably know this by now but maybe one of you could just take a few seconds to analyse it the very first pin is going almost directly to one of the legs of the laser so I'm at the stage of doing some digging myself and analysing a few laser circuits to see if there's any similarities here regarding a direct path from either positive or negative directly to the laser to help me figure out the polarity

Oh by the way the teeny weenie little LEDs on here are probably the brightest things I've ever seen I haven't even turned them up to 12 volts just at 10 volts there blinding meanwhile they're probably a 1\5 the size of a 555 timer

Just the LED powered up.    soon to be that laser diode

It´d be much better to have only one thread in this forum. Posting the same pictures to different (sub-)forums makes everything very chaotic.

I could tell you quite a lot about the laser part - I´ve worked for years on this technology. But if you have no experience with lasers then it´s one of the worst of all bad ideas to mount a non-safeguarded class-4 laser on the front of your motorcycle. I have no ideas about Canadian law but beside legality this is just something that someone professional can not support - sorry.

It came out of a car it has the original reflector everything will be original How it was mounted in the car.  your help would be appreciated.   I just need to confirm it powers up and then reassemble everything.  how Dangerous can A car headlight be.  Sure its a laser.  BUt.  its also a headlight. in the original form how manufacturer provides it. 

it was a canadian Car.  There are no laws that regulate this.  Every super car Around the world has LAser headlights.  u should know this if your EXP in this field

just to clarify to every one.  This laser "headlight".  Is used in a production car, all my parts are Completely intact Perfect condition.  i have The entire Assembly To house this.  with both lenses in original form.  And thats how it will be used..    Essentially. your helping me Fix my cars headlight.. Which happens to be a laser...

you can see in attached picture 3 reflectors two for leds.   And The long Skinny one for the laser diode
