Welcome but you're not giving us much help (even the photo is blurry, sorry so lots of faults I can't read but perhaps glow plug related or not!)

What is the history, symptoms etc in case that would help someone else can point to the exact issue and how to solve it? 
It looks like a fault in the glow plug module so that would need investigating first?
It can have various effects on starting, running, and DPF regeneration amongst others.

I've tried two pairs of glasses and I'm still none the wiser as to what I'm supposed to be seeing 🤔

The FOC admin don't charge per word (yet) so maybe you could start be detailing the problem and posting a photo we can actually see?

You don't want a modified sierra ? What sort of ford enthusiast are you man?? 

I'd say AI but am prepared to be wrong.

I don't think there's the packaging space under the bonnet to have those wings

At least it has a (few) spare wheel. Plus chrome plated parking assistance.

Judging by the exhaust headers I think the packaging under the bonnet has also been rearranged a bit.

You'd have got away with it with Cortina but not Sierra as it had McPherson Struts

Plus front wheels are too far forward

One whose Sierra has only one mod - a Group B head gasket......

(Although it has a temporary fit of a Sony CD player.)
