I attached a task light like that to my MFT along the back on the offcut side of the guide (so, far right corner). Just a block of scrap Oak with two holes through it for T-bolts that were put in the T-track on the side of the MFT; screwed down with two thumb screws. For the top of the block, all I needed was a hole sized for the rod at the end of the light. It is very easy to remove, though I rarely find a need to do so; just lift it out of the hole in the block as the block is below the table surface. It is very useful for seeing anything you are lining up with the guide rail or, say, router markings. Mostly what I use it for is putting the light very low while sanding; the raking light makes the scratch marks very very obvious. Actually, it's well worth it even if you only use it as a raking light.
