I really like the idea of the unit that American Classic, our sponsor, sells. The main selling point for me was to keep it as stock looking as was reasonably possible. The kit that they sell has only a small toggle switch under the dash on the small lip, with a flasher to make em blink, and a buzzer to remind you that it's on-all out of sight. You wind up replacing the sockets in the front and rear with new ones that have two filament connections. The front ones are a little more of a pain because you have to drill out the rivet holding them in the housing. Personally, I think that the signals are most important in the rear, so I haven't done the fronts yet, and as of now really have no plans to. One small note...all of the parts are available from Radio Shack, and to put one together yourself would save you 20 or 25 bucks, but their kit including the wiring is still only 45 or 50, if memory serves me.
