Correct. I have a small felt pad in the back of my stock housing to dampen vibration, and i could tell where the LED housing likely bumped up against it snug. So there is room for a fit without forcing anything, but not a lot of EXTRA room. The little capacitor deal (or whatever the rectangular thingy is) just tucks up in there with all of the other headlight wiring.
Note that they do get warm, which halogen bulbs do as well. Just be conscious what you have up against the LED parts (that silver thingy) in the event that it gets hot enough over time to possibly melt any wire sheathing and short something out.
Dave likely knows better than I what the potential for this is given that I have not ridden with the LED for any extended period of time and he has tested a lot of stuff, but I am also admittedly overly cautious when dealing with electrical components that get "warm" since electrical stuff isn't my strong suit.
