Has anyone ever installed or used LED Door Projectors or LED Ghost Shadow Lights before? They are the lights that once you open your door, the light projects an emblem or logo on the ground. Because I have recently purchased a set of LED Door Projectors. They were supposed to come with an install guide. Well the install guide is vague and pretty much garbage. The install guide is literally on the back of the box and reads as follows...


Step One: Remove the Door Panel
-Snap off the panel located on inside of the door

Step Two: Use the Hole Saw
-Drill out correct size hole fro projector light

Step Three: Wiring to Power
-Connect red and black wires to ground and power

Which sound very simple but are also very vague. There is no actual guide that walks you through the instillation process, especially with hooking the wiring up. To be completely honest I have no idea where to begin with wiring these lights. I had a couple thoughts about wiring them to the lower interior door lights on the door, but have no idea about the ground. Like, if I could just wire the ground to a metal part of the door. Kind of like when hooking up an amp for subwoofers. Like I said though I'm completely clueless. So any and help would be much appreciated along with any diagrams of what the door would look like with the panel removed or anything along those lines. I just don't want to do anything that would fry my electrical system or catch my doors on fire.


PS: Sorry if there is a thread addressing this issue, I couldn't find one.
