Just had a Viper 3305V 2 way alarm professionally installed. Armed car remotely. Bright flashing blue light on constantly when armed. Will it drain my battery overnight? Please help. Thanks.

im a service manager at a Subaru dealer. The security system is in valet mode. Open the drivers door, with the drivers door open hold the small unlock button on the remote and keep holding it until the light stops flashing.

Sounds to me like the parking light output wire. They usually have a seperate fuse or the connection is bad. The connection on your vehicle should be behind the pass side kick panel and look for a wire to the white/purple wire and check that with a meter or light to see if it's kick out power. There is a possibility they used the negative trigger through a resister and that would be located behind the headlight switch. That will at least let you know and trace down the problem. Here is a link with that parking light info for yours. Hope this helps and let me know if you have more questions.

Mine acts the same way. I found that it doesn't alarm unless you trigger the alarm. Be sure to check that the alarm fires correctly as mine didn't and they covered this under warranty.

Yes the best way is disarm the alarm and put in a Valet Mode
To activate the Valet Mode do the following:

There is a push button or toggle switch to disable the alarm (to engage the valet mode). Without knowing where this
switch is you won't be able to disconnect the alarm.

1. Put the key in the ignition and turn it to the "on" position.
2. Flip the toggle or hold the push button for at least 5 seconds.
3. The LED. light will stay solid on.
4. Turn the ignition off
5. Release the push button. If you have a toggle leave it alone in step 2

Turn ignition to the ON position, press and hold the valet switch under the dash. It should turn the LED light on solid
