OK, but not Great....
I put the Creativair lights (2" halogens) in from the start, because I didn't really want to cut into my QB leading edges. Once you get the kit, you'll be surprised at how little material you get for the price - I am not advocating stealing someone else's design, because they are entitled to sell anything they want for whatever they can get, but if I wanted to do the same thing again, it would be easy to duplicate.
The bottom line is that it is nice to have the little streamlined lights in the tip, but they really don't give very much light. I generally get more help from the runway lights than from the landing lights. they are adequate, but just barely - if you like lots of light, these are not for you.
I have thought about converting to HID's in the same space, but haven't decided on spending the money yet.
