Gadget Freak Case #119: Take Control of Your Car’s Interior Lights

Bill Bowden takes the mystery out of a new car's interior lights with his bright gadget

By Design News Staff -- Design News, April 28, 2008

When you close your car door, the lights may go out immediately, fade or they may stay on interminably while you stand there wondering if you closed the door all the way. Bill Bowden has devised a gadget that lets you take control of your interior lights. Bowden’s Automobile Interior Lights Fader lets you determine whether the lights go out right away, fade or stay on for a few seconds. You can even program the fade times to fast-on, slow-off or vice versa. The device’s circuit is intended for cars that have a door switch that supplies a ground to the interior lights with one side of the lights connected to the positive side of the battery through an appropriate fuse. With a few modifications, the device can also be used without a door switch.
