One of the funnest aspects of the airplane build is planning.  Half the stuff you want you can’t afford but it’s still fun to plan.  Since I would like the new aircraft to be able to be operated at night I will need navigation lights.  Since I would like the new aircraft to be operated during the day I will need anti-colision lights or strobes.  An aircraft builders group I belong to is offering a group buy on these:

They are pretty cool in that the power supply for the strobe and lights is built into the lights rather than having a separate power supply.  They are self-contained and come with a lifetime warranty.  Can’t beat that.
