This LED brake light was developed from comments and feedback from the
356 Porsche registry. It contains 10-10mm superbright LEDs and has a
dc plug and jack for easy attachment and removal. It also operates with
equal brightness on 6 and 12 Volt vehicles. When power is applied, the
LEDs flash for an adjustable period and then go steady on. For more
