AUTOMOTIVE_NEON_DRIVER

A 555 timer drives driver transistor Q1 and switching transistor Q2 at 25 to 30 kHz. T1 is wound on a ferrite core (try using a core from an old B/W TV flyback) and has the windings arranged as shown in the schematic. About 2500 Vac p-p is produced, so be careful to avoid any possibility of contact with this voltage, as it can cause a bad shock or RE burn. The neon tube is a custom-size item that can be made up at any neon sign shop or possibly purchased commercially. It is not legal to illuminate certain parts of your vehicle in some parts of the United States and in some nations.
