I'm familiar with this issue--it gets even more expensive when an airplane is envolved. I'm an officer in a Chicago-area flying club--we do our own oil changes and other maintenace that pilots are allowed to do, as opposed to FAA-certified mechanics/technicians.
The problen is that the white tail position light (running light) is mounted on the rudder--the moving part not the stational tail fin. With age and lots of flexing (it is a major control surface!) the wire breaks. Pilots are allow to change the light bulb but not trouble shoot and repair the wiring. We trouble shoot, but a certified technician is required to solder the wire, and now you have a hard splice, just like the car stereo. It's about a half-hour job, and we have one or two Airframe & Powerplant licensed mechanics in the club so it was easy to make the airplane legal at night.
Linear guides are one of the most important components required for the design of automated or computer-controlled equipment. Aluminum profile extrusions, used for these guides, can enable designed-in functional features.
