Headlight buzzer installation

But on a side note good idea for vehicles that are not pre wired. Nicely done. You could also consider putting a buzzer in the engine compartment wired straight across the side lights, which should make it easier to find the wires and not need any other circuitry.

The idea is to mount it somewhere where it can only be heard outside the vehicle if you leave the vehicle with the lights on. It will of course be running all the time the lights are on, but if you get an appropriate volume one it won't be heard when the engine is running anyway. For someone who wants to get a third-party add-on, we have 'Headlight Left On Reminder' kits available at 'liteminder. Introduction: Buzzing Headlight Reminder.

By CBGjr Follow. More by the author:. Here's where the rubber meets the road, so to speak After inspecting my fuse box I found two fuses that would work perfectly for my needs. Again, I didn't want to splice into my existing wiring harness or go digging around. There's a 5amp fuse that powers my dash lights.

Really only on when my headlights are on. Ok, ok, ok, yes. I could "theoretically" turn on my dash lights on their own. No one! Ok, enough said. Moving on This would be perfect to provide the 12v "headlight on" voltage to my buzzer. The second fuse was the 15amp for my radio. The radio is only powered when the truck is running so this would be perfect for my "ACC" connection. Power from this connection would keep the buzzer from, well, buzzing, when the headlights are turned on and the truck is on.

I attached the ground to a bolt securing the fuse box to the frame. Everything was now in place. With all the wires connected, nothing happened. For once, I was happy for nothing happening.

I powered up the truck. No buzzing! So far so good. Next I turned on the headlights. Still no buzzing! Things are looking good so far.

Big test time. I turned the truck OFF. I turned the lights off and the buzzing stopped. It worked. I mean i kinda knew it would work but there's something eminently satisfying about something that goes from a need, to an idea, to a fully operational "thing". I tested several more times and everything is working as I had hoped. Just to make sure, I tested all the contact points just to make sure nothing was draining anything and when the truck is off there's no bleed voltage anywhere.

I only have one real concern. When the truck is running the relay coil is active, moving the contact from normally closed to normally open. I have no idea if this will be a longevity issue or not but it's something I'll keep an eye out for. If it breaks, worst case scenario, I just have to pull a couple of wires and it's "deactivated".

I had thought about wiring a manual override switch, just in case, but since the wires attached so easily I didn't think it would be a problem if it came down to it. All an all an easy build that didn't take long at all and provide an invaluable, to me at least, service. Go out and build something! Did you make this project? Share it with us! I Made It!

Happy with the product. Mine's a '97 miata. Maybe I'm mechanically challenged or something, but I had some troubles installing this. Normally, they're U-shaped and will wrap around the fuse pin when inserted, but this again seemed much too fat to fit in the fuse box.

Just as well that the outside of the U broke off during the dremel attempt. Also, I soldered the black wire onto one of the insert pins after cutting the dopey alligator clip off. I chose that because I don't want to leave the running lights on either -- I'll change it later if the need arises.

Use the headlight relay instead if you want to be able to leave the running lights on without the buzzer. I just know there's a better place to grab the positive for the buzzer, but I gave up trying to find it. I'll most likely try using some epoxy putty to stifle it down a bit. I suspect it'll work fine on the other models as well. Members Search Register Login. Joined: May 14, Back to Top. Thinkster Copper - Posts: Joined: March 27, Location: United States.
