Head Lamp control by the
shifting lever - This circuit causes the operation only when the head
lamp is lighted by 'IC Con-Light'. Because, in the case of operation by the usual lamp switch ( combination swtch ) , it is
to do as the head lamp. . . . [Seiichi Inoue's Web Site]
Head Lamp illumination
confirmation device - Circuit where I introduce here it checks the
normal operation of the head lamp and warns to the driver in the case that the electric bulb is not lighted. . . [Seiichi

Head Lamp turn on dimly - In Japan when the momentary stop is done with intersection at night, the head lamp is turned
off. The circuit where. . . [Seiichi Inoue's Web Site]
Headlight Alarm - "Never forget to turn off your head light ever again! Most newer cars already have this
feature built-in but there are still lots of cars out there without it. This simple circuit is cheap and can be built for
about $5 bucks!". . . [Tony van Roon's circuit]
Headlight flasher - . . .
Headlight Flasher - This circuit was requested from an email. It will allow your car headlights to flash on and off
at the same time or it will cause them to flash alternately. The circuit is based on the 555 timer. It is used in the astable
mode. The 555 timer. . . . [Circuit by Randy Linscott]

Help Protect A Vehicle-Reverse Camera -
10/06/11 EDN Design Idea Add a delay to prevent short power pulses as you shift through reverse. The circuit in this
Design Idea uses a simple comparator circuit to make a power-on time delay for an automotive rearview camera. Auto
manufacturers typically power reverse-view cameras from the reverse-light circuit. In automatic-transmission vehicles, a
short power pulse is applied to the camera when you shift through reverse as you go from park to drive, or vice versa. . .

Hijack alarm - . . .
Hijack Alarm - There are two alarms here, be sure to scroll down. The first circuit was designed for the
situation where a hijacker forces the driver from the vehicle. If a door is opened while the ignition is switched on, the
circuit will trip. After a few minutes delay, when the thief is at a safe distance, the alarm will sound and the engine will
fail. . . [Circuit designed by Ron J]
Improvement of the power
windoW switch - Most of the car in Japan ( probably your country also
) are equipped with the power window. The power window does not operate when the engine is stopped.
There is reason in order that the power window operates. . . . [Seiichi Inoue's Web Site]
Indicates Automotive Electrical Voltage - When troubleshooting the 12v electrical system of an automobile, it is nice to have a simple
voltage indicator tool instead of a voltmeter. This electronic circuit, hobby circuit is powered by two AA or even two N
cells, which will provide enough energy . . . [Hobby Circuit designed by Dave Johnson P.E., 07/09/06]

controlled appliance in another room. . . . [Andy Collison's website]
Inside Story: Audison
LR604XR Amplifier (Car Audio) - Of the few car amplifiers I tested,
gutted, decyphered and fixed, this one seems to be the best in design quality. Too many car amps (although solidly built) are
apparently designed by computer class students, too many traces, too many vias, absolutely wrong component placement etc. And
on schematic level, their different functional parts look like a newspaper clip collection. If the amp . . . [klausmobile @
