Although, most of the car electronics have evolved into solid-sate versions, a turn indicator flasher unit is one device which still depend on a relay based design in many of the modern cars. Disadvantages of Relay Based Flasher There are a couple major disadvantages of a relay based electromechanical flasher unit: 1) First, these being […]

220V Dual Alternate Lamp Flasher Circuit
This is a mains operated transformerless flasher circuit that can be used for alternately switching a couple of CFL or similar 220V/120V lamp to produce a decorative lighting effect. Circuit Operation The below shown design depicts a simple mains operated dual or alternate lamp flasher, which is designed to flash or blink two mains operated […]
Make this 2 Pin Bi-Color LED Flasher Circuit
This transformerless mains power supply circuit will allow flashing of a Bi-color 100 LED string, in an alternately switching red, green effect. Using 2-pin Bi-color LEDs The proposed circuit can be used as a Bi-color LED flasher, for generating an alternate red, green flashing effect over a string of 100 LEDs. Bi-color LEDs are available […]
Morse Code Flasher Circuit for Lighthouse
In this post I have explained a simple morse code lamp flasher circuit which may be used for model lighthouse signalling applications. The idea was requested by Mr. Frank Gardner. Technical Specifications I am in need of a unique flashing circuit. I have built several exact scale models of the light house at Yerba Buena […]
Car Turn Signal Flasher Circuit with Lamp Malfunction Indicator
In this post I have explained an automotive/car turn signal indicator circuit idea with a built-in load malfunction indicator, meaning an additional LED lamp fitted on the dashboard which would warn if any of the side indicators went bad or fused. The idea was researched and requested by Mr. Abu-Hafss. The Circuit Concept I have found a transistor-based flasher including a […]
Mains AC Xenon Tube Flasher Circuit
In this article I have explained a very simple yet amusing mains operated xenon tube flasher circuit using ordinary electronic components. Circuit Operation The circuit was taken from one of the old elektor electronics magazine and it is indeed a very cute little circuit which may be used for creating high intensity lighting effects during […]
