they are overlays, and I would consider priming over them, but they really dont stick up too much, and if the bike goes down im pretty sure that these LED's are going to be the last thing i give half a sheize about.
regardless, they are bumped up, not dramatically though... looking from afar you can barely see it.
the one thing I hated was that for the actual wiring input for the LED's the covering was white--- completely the wrong color for my bike...
.. this was even worse when on my left side (sitting on the bike) the LED didnt wrap all the way around, so part of the covering is slightly showing on the side.
I just primed and spraypainted it, let it sit, and you can't even see it without getting up close and personal.
