How to use existing dash board control switch of Fog lamp in to Fog lamp and DRL LED's ?
Greetings of the day, You are doing a wonderful design and support to this forum. My best wishes.
Am looking for a circuit which is directly connected to the fog lamp output from car dash board. The circuit will control Fog and DRL lamps together with single switch, and do switching to my response without modifying the old switches.
Car-Fog light when switched one time ON and OFF, will switch ON the fog light continuously,
Car-Fog light when switch two times ON and OFF the fog light is supposed to go off and DRL LED illuminate and stay ON continuously.
I want to reduce extra control switches & cable loops inside my car. Pls support thanks in advance. Email: firstname.lastname@example.org
Here's the design you asked for.
How the Circuit Works
The main purpose of this DRL and Fog light changeover circuit is to allow a single switch operation for selecting the fog light and the DRL light in tandem, without having to depend on any other external switching arrangement.
Here when the fog switch is first turned ON and OFF, the fog light is switched ON. On a subsequent ON and OFF of the fog switch, switches OFF the fog light and turns ON the DRL lamp, on further toggling, the fog light yet again switches ON extinguishing the DRL.
In order to reset the system, the fog light switch could be held in the ON position for a couple of seconds. This will reset the whole circuit so that a fresh cycle could be initiated, although this may be never be necessary, since just a couple of simple operations are involved in the system.
It must be noted though, that the selected lights will be flipped-over and continue to remain ON, only while the fog switch is in OFF position. Keeping it ON will switch OFF the circuit and the lamps permanently.
