VX "headlight on" signal question

[dogncatboy]

This question is about the alert sound you here when the ignition is off and the headlights are on. From looking at the diagram, it appears that Honda put the light on signal in with the stereo. I believe that the red-black wire is the light on signal, but I don't see a ground associated with it. How does this wire in to the stereo... or am I way off base? I am afraid that I will be stranded because I am a knuckle-head and will likely walk away from the car with my lights on like I did yesterday. I was lucky in that there was enough juice to turn her over, but I might not be that lucky next time. Any advice on how to get this working would be greatly appreciated.

I've jump started mine on a couple occasions because I left the lights on. I have some jumper cables in my car for when that happens. The beeping noise that the car makes when you turn it off seems to have no bearing on headlights. The VX does not have head light sound warning as far as I know.

A agree. The VX has NO reminder for when you leave your lights on. Do a search on Honda-tech and you should be able to find a how-to to wire one up.

You can hook a buzzer up to such and such fuses in the fuse box to go off if you leave the lights on, not hard at all.

Easy for you to say, I'm electronically challenged! Do you have a diagram or some ideas on how? If I hook it up to the light fuse it would ring while I was driving with the lights on, right?!! I am open to suggestions.

I forget exactly how to do it, but I think you hook the power side up to the fuse for the lights and the ground up to something to only becomes grounded with the key out, like the rear defroster or something? I forget exactly. Just mess around...

Hook it up to the dome light switch and light PW output. Ehm... Get one of those $1.50 relays (damn u inflation11!1 ) und hook the PW up to the light fuse, unless it's relayed, then use the relay output, so if the lights are on when you open the door the current from the dome light being on will engage the relay, which will trigger the buzzer, or blinky light, or whatever ya wanna put in to alert yerself to lights on+open door from the powered lights. GND goes to GND, w/ the +12V from the active device and power going to the thing that alerts ya to it's activity.

Go to Radio Shack or similar store for piezoelectric buzzer for $3. You will need to find out which fuses apply for your car since the 91 civic did not match my VX. It's easy enough to find - the fuse descriptions are on the back of the fuse cover.

I have not drained by battery since I installed this!

Excellent info. Thank you for the link. I will get a chance to try it tomorrow.
