Began installing the Duckworks Wing mounted lights. I decided to go with the 100W halogen because of cost and the amount of night time flying i do. For the amount of night flying i do, i can replace the halogen bulbs for 3 lifetimes and not come close to the cost of the HID bulbs. The installationis basically the same. I also AGREE w/ Dan Checkoway who said that the statement that these can be insatlled in just a FEW hours is misleading. I spent 6 hours on just the Left wing yesterday, and stil have to trim the lens. I suspect that having already mounted the Leading edges causes some additional time, but not all that much. All in all it's a very nice kit and will look really good. I originally planned to use the Van's lights that mount in th wing tips. but I found some LED nav/position lights that I think are awesome and they use that space.
This wasn't as agonizing as I thought, used Dremel cutoff wheel
