So I've decided to make my first project with carbon fiber a difficult one(not smart?). Ill post pictures as I progress and advice as to what I'm doing would be appreciated.

The idea is to make a mould that wraps around the edges as they can be seen while on the car.

The clay in the front of the light is to fill in the cosmetic groves that the carbon probably wont lay into, should I just fill them in with Gel-coat and sand them off the mould, or try to fill them in like I have now? The clay is hard to smooth out nice and ill probably have to sand anyway.

I would like to make this a repeatable process because I'm practicing on a used pair of lights first and if it comes out good Id like to do mine.

prep for mould making so far

To be fair, apart from the defects youve highlighted, youre probably not that far from getting a decent surface finish. Just practice now getting it into all the corners.

Remember its a non stretch fabric, therefore it will try and ripple/fold when put onto a complex mould like yours.  Even distorting the fabric will still risk creases.

You can use spray tacks, but it will effect surface finish slightly meaning youd have to lacquer the part.

I still think you need cut lines at the very least horizontally across the light openings.  Imagine viewing the part from above and trying to place a piece of kitchen towel or similar on top.  It has to drop a long way between the top and bottom of light appertures so will cause creases/folds at the edge if you force it in.   You are already trying to stretch the fabric around the curves as it is.

I wouldnt throw away mould just yet!! remember you can use a big piece of carbon then trim it and use tape to hold the edges in position, although not too much tape as you want a bit of movement when you pull a vacuum.

Remember youre doing a complicated shape for a first part.  Had you done something simple, youd be there by now. But dont get too disheartened as by the time you get it right you will have learnt a lot more than doing a simple panel.
