I wanted to add lighting to my A1 but the LED bars I found didn't work. I took two different models and remixed them into one that works out well for me.
This mounts to the X axis mounts on the left and right, and it holds the LED bar back far enough to avoid the Z axis rails.
I used this LED bar https://www.amazon.com/gp/product/B0C5N869QZ
Hope you enjoy!
