Well there's some bad news about utilizing the "triangle areas" of the lower grill, primarily that its a whole piece connected with the rest of the grill. The chrome part is actually separate from the grill frame itself--and utilizing those outer corner parts is basically not an option since installing a lighting fixture there would require dismantling the entire thing. Additionally, you'd have to cut a hole or cut out the entire thing for installation. This isn't ideal, especially since taking everything apart can be extremely difficult due to all the tension-style plastic clips. In my estimation, this whole thing was made to snap together but not be taken apart. Something WILL break if dismantled. Alternatively, we could make something that drops in from the front, but that's still not a great option because at the very least it too would require drilling a hole. We'll continue to look at other ways to utilize this area and I'll post up if the brainiacs come up with anything.
As for the side vents, I'll likely make up a prototype and install on my car so we have something more than a Photoshop to go on. If people like it, we can see about having it mass-produced. In the meantime, an LED insert for the silver vertical piece is currently being worked on.
