ya I would need to look into a few places. I haven't seen the bumper step one your talking about though. I want them to look natural and not an add on, if that makes any senseI guess it could be done but I would be concerned with putting lights in a "contact point" for your rear bumper where they could be easily broken in a parking lot mishap etc. Or that you would be drilling into 20 year old plastic that could lead to cracking and need to replace a large part of a rare color and style of AV cladding.
How about trying an alternative less invasive mounting like under the bumper?
those are all nice! that last one is what I was hoping to do...but looks like all 3 would have to cut the bumper anyways. thanks for those linksNot cubes but here are a few links to the Step Bumper light mods
