turn on lights when alarm armed?

Hello, I have a 2004 Chevy Avalanche and one feature I really like is when I lock the doors it turns on the parking lights/reverse lights for 30 seconds or so. I am planning on installing an aftermarket alarm in my '93 Corvette. I've searched and searched but I cannot find where any aftermarket alarms feature this option? Can anyone tell me if the top of the line DEI security systems have this feature? Thanks,

You would have to add it - you can do it several ways, but the easiest would probably be a DEI pulse timer connect to the lock output of the alarm. When the lock output pulses it can trigger the pulse timer to turn on for 30 seconds. The contacts of the pulse timer can drive the parking lights / reverse lights / head lights / etc.Kevin Pierson

Thanks for the answer that is exactly the info I was looking for.

Kevin, wouldn't you need at least one extra relay or a pair of diodes, one 3 amp* for the reversing lights and one 3 amp for the side lights. 508d. BLACK/ white from alarm's lock pulse. Black to ground. Red and yellow to constant 12V+, fused at 20amps. Orange not used. Brown via diodes, bands (cathodes) away from 508d towards lights and reversing lights. * 1N54XX diode.

Since I'm not familiar with the wiring of that vehicle I didn't go in to details of how to hook up the contacts of the pulse timer. You would need to keep all the signals isolated for sure!Kevin Pierson

Howie, me thinks you have a typo error. the 508d is a motion sensor. Maybe you ment a 528t?When all else fails, Read the Instructions

You think right luckily certain things are joined to me permanently I meant of course 528t.

I have connected this type of setup on my 2000 Ford Taurus Wagon and it works, BUT, the diode get very hot. As in untouchable hot when the 528t is triggered with the unlock.   Is this normal for the diode to get this hot?    Have I connected something wrong?    I know I have the correct wire to the back up lights. BLACK/ Pink in the drivers kick panel, as when I cut that wire, no back up lights.

I have connected just a tail light bulb the the brown wire with the diode, grounded the bulb, hit the unlock trigger, and still the diode get hot. 

Red and Yellow to 12 volts constant, Black to ground, BLACK/ White to unlock trigger, and Brown to back up lights (BLACK/ Pink)

What is the part number for the diode you installed? How much current do the headlights pull? How much current do the reverse lights pull? You may be better off using two additional relays - one for each set of lights, for the isolation over the diodes.Kevin Pierson

X 2 with KP, also if just staying with the diode, use an 2N54xx not 1N4xxx. 2 x rev lights a 21watts =42watts divide by 12 = 3amps +!
