Lights on reminder

I’ve left my lights on too many times and came up with a circuit that I could add to a vehicle that does not have a lights on reminder to help me remember when I leave the lights on.  In essence, a tone sounds when the door is opened and the lights are on.  I also added a “shutup” switch that can be used to turn the alarm off in the event that the door must be open with the lights on.
 
I added this feature to quite a few of my vehicles over the years and it’s saved me quite a few times.  There are two variations of the circuit - this one for vehicles that apply power to the interior courtesy lights when the door is opened and another (not shown here) for vehicles that apply ground to the courtesy lights when the door is opened.

Re: Lights on reminder

I put one one my mustang while I was redoing the A/C. Works good. I need to put in that on -  off switch but I"d probably forget to turn it back on. I got the factory reproduction part. It's not very noisey as the reports say.


Sometimes ya just gotta fly low.     70 convertible 76B model, L code out of the box. 416W stroker now.

You don't need to turn this one back on.  It "rearms" itself when the door closes.
