Finnaly somebody who kinda thinks like me, anyways this I plan on doing to my car when I'm done with my alarm or starter, if it's a starter, underbody LEDs will stay on as long as the car is remote started, they will stAy on when I unlock the car for 30 secs, and will flash when alarm is triggered,
If it's just alarm the LEDs will stay on after unlocking the car for 30 secs, flash when locking or whe. Alarm is triggered.
My advice is that you wait till you install you Alarm, the options are endless of you know how to use your relays and diodes. I'll be posting a how to when I'm done with mine.
