however, if you make this connection, the LED turns on as you turn off the car, instead if you take the positive power from Pin 1 explained in post 1 of this THREAD, it works only when you close the car.

I tested it out and this works perfectly, you can adjust the length of blink and the pause seperately so it easy to sync according to an original alarm.

have you always connected to pin 1, of the first post?

I wanted to ask you, if I use this pre-printed circuit, which has a power supply starting from 5v, if I connect it to pin 1 which has, when the machine is switched off, 4.6v, which you think is off in this circuit or is powered and makes the led work even with a car?

Below is a picture of my final product. I am still deciding whether it needs a small case to fit in, but I think it will be OK as is.

I had retrofitted my original mirror with a UGDO/Auto dim/Compass version, so I had that mirror to use on my bench for testing and delay set-up. What I found was that if I had the R1 resistor set at half its range and the R2 at about 1/8, I got a 3 second delay and a nice flash.

Most of the parts I bought online through mouser.com. My cost for the prototype is probably about $100, but there were a number of “initial” things I needed to buy to make the PCBs and be able to test them.

If anyone is interested, I would be willing to produce these for sale to the general public. I was thinking about $20 each including shipping in the US.

Let me know. I have a video I made of mine on my bench prior to install which I may post later.

You selling it still ?
