Tools/Parts
1 12v Piezo Buzzer (Not Siren!) (less than $3.00)
1 pair of needle nose pliars

Instructions
Take off your Fuse Panel so you have access to your fuses. Next unplug the #8 Taillights/License Lights/Instrument Lights Fuse. Once the fuse is unpluged take the Red Wire from the Piezo and place the exposed end down into the Fuse Housing where the metal part makes connection with the fuse. Then plug the Fuse back into place, make sure it is in all the way and the wire is not in the way of it.

Once that is done unplug the #18 Rear Defroster Relay Fuse. Do the same as you did for the Red Wire for the other Black Wire and make sure everything goes back in correctly.

Now to test it make sure the car is turned off and then turn on the headlights and when they come on the buzzer should buzz. Then turn the car on and it should stop buzzing once the car is on. The buzzer will help you to make sure to turn your lights off so your battery is not drained.

Notes
I tried using a Piezo Siren but it didn't work. I'm not sure why though. But these are the correct instructions for installing them into any 4G Civic/2G CRX.

If you are doing this for a car other than a 4G Civic/2G CRX make sure to use the fuses that work for the same functions as listed above and it should work.
