Probably not your typical lighting accessory question. /ubbthreads/images/graemlins/grin.gif
The rule book says I must be able to dim ALL supplemental, forward-facing lights with the high beam switch. I'm planning on running a pair of pencil beams and a pair of euro, or wide, beams on the light bar/pod PLUS the factory fogs. Here's where the logic problem begins.
The pencils will have their own on/off switch.
The euros will have their own on/off switch.
The fogs will have their own on/off switch.
When the rally light switches are turned to ON, activating the Galant's high beams with the stalk will ALSO activate the rally lights (all six of 'em, including the fogs), otherwise, it's just the factory high beams.
Now, here's the tricky part, methinks. I also want an override switch, which will allow me to bypass the factory controls in case of emergency or whatever. As we all know, the headlights turn off with the ignition. If something goes wrong with the OEM controls, I want to be able to bypass them and still run the lights.
Throw in the factory harness always providing 12VDC to the high beams and merely switching grounds, and this project got me all confused. I'm looking for some feedback and advice on the attached schematic I sketched out today.
From L to R: left/right wides, left/right pencils, then the FSM schematic layout of left lo - left hi - right hi - right lo. (I did not include the fogs on this, though I suspect it will be another iteration of the solution for the pencils/wides.)
This schematic still shows things enabled by the ACC switch, but what are your thoughts on the way I've got the pencils/wides wired in? I'm using the voltage applied to the headlights as triggers on the pencil/wide relays, which pull their power direct from the battery, and since the headlights always have 12VDC, I'm just providing a shortcut to ground there to bypass the control stalk if desired.
Additional, potentially useful information: These switches will be mounted to the center console, likely where the radio used to be. Thanks, gents. Appreciate it.
