I’ve changed my estate’s boot lights to these 2 years ago:

the change in light output was huge. But, as my car is a estate, it resulted in better illumination of my rear bumper. I wanted te light to shine into the boot.
Now with the day’s getting darker i wanted more light. So i ordered 2 more lights and went to work.
Now I am waiting to a loom connector and i need to find a place to tap into the existing wiring. Looking at the detachable flashlight..
