blinking angel eye

since the relay is only needed for the purpose of changing polarity and not to amplify current, why not just connect the switch after the relay has changed polarity, that way you can switch it on and off whilst you're sitting around, and driving, and you can leave it on when you want it to flash with your alarm, doing it this way though will only allow you to turn on the angel eyes when the parking lights are on, whether the car is on or off, if you had another way in mind as regards to the manner in which you wanted it to work post back,( or if you had that idea already, read my screen name underneath.)

Here's what I came up with:

Basically, if the ignition is off the parking lights will control the angel eyes.  If the car is running the parking lights will have no effect on them.  This provides no protection if you were to walk away from the car with them turned on, since you stated you wanted them tied directly to a constant hot wire. 

The second relay simply converts the polarity of the parking light signal to be a (-) to work with the constant hot.  If you switched the ground instead of the hot you could eliminate the second relay (the one one the right).

The relay on the left will be completely energized, it shoudln't buzz at all - it will have 12vdc across the coil.

He requested the the ground be switched and that the lights be fed with a constant hot feed.

are you positive about that,(i use the poles in reverse as to the way you do, i dunno if it makes a difference, so it could be my ignorance) yes it will have 12 volts across the coil but only when the parking lights are on, but when it's off i mean, like during the day, and i meant about eliminating the second relay he would have to switch the hot instead of the ground, again correct me if i'm wrong.

thanks for the help so far guys i just gonna try to better state how i wish to try to get this to function.  I would like the angel eyes to blink with the parking lights when the alarm is armed or disarmed, but at the same time be able to turn them on or off while the car is sitting and not running or have key in it at all. so basically i would normally hook it up to a switch where it will turn on or off anytime via the switch, i just want to add the ability of flashing with the alarm without compromising the function of controling it with the switch any other time!

Thanks again guys

you dont even need relays. just use a couple of diodes to do what you want. below is the diagram.

ok then here's what you do, using the diagram underneath, the positive trigger is what you're connecting your parking lights too, then between the negative output wire from the relay and the ground input of the angel eyes insert a 3amp diode with the band facing towards the relay, then using the on/off switch, connect one side to a ground, and the other side taps on to the ground wire of the angel eyes with a diode in between, band facing the switch, if you don't understand, post back, i'll see if i can post a diagram.
