What?

Rolls Royce vehicles can come with an optional starlight headliner that consists of about 1000 individual LEDs. I was able to do the same for my Micra but with 200 LEDs instead.

I used the following fiber optic LED kit: https://www.amazon.ca/gp/product/B01...?ie=UTF8&psc=1

There are cheaper kits available on Amazon, but I chose this one because it has the "twinkle" feature. The light module utilizes a plate (with several holes punched through) attached to a motor that creates a twinkling effect.

My phone is not the best at low light video, but this attached video shows the effect clearly:

How?

For power, I decided to utilize a cigarette lighter inverter and the provided 12V power cable. I am sure that it is possible to hardwire the module, but that is outside my area of expertise.

Here is a link to the inverter in case you are interested: https://www.amazon.ca/gp/product/B00...?ie=UTF8&psc=1

The installation process is relatively simple but can be time-consuming. I started by removing my headliner from my Micra. Then I marked and numbered places where I would insert the lights. Next, I created the holes using a pushpin, inserted the fiber optic wire, and used a hot glue gun to keep it in place. Finally, I cut the wires flush to the headliner and reinstalled it into my car.

I followed this video throughout the installation:

Here are a couple of pictures I captured during and after the installation process.

I will try to take some better pictures of the lights this weekend.
