Need help modelling headlights and taillights

I was working on modelling the Tata Hexa 2016 sold in India. I am stuck at the headlamps and tail lights. The car has projector headlamps and black inner walls of the headlamps. At the rear, it has a continuous red tail lamp, multiple LED brake lights and a normal turn indicator and reverse light. What is the usual workflow at modelling this so that it looks realistic with the glossy/glass cover and accurate light emitters. I am using cycles on Blender 2.83. I guess I’d have to start the lights from scratch to get them right.

The headlamps on the real car

The tail lamps on the real car.

Just a good workflow to get this right would be very helpful.

Thanks a lot!
