545t delay

Ok I have a 545t I had it installed on another car before and when i went to sell it I removed it. I now want to put it on my 1998 Chevy Astro. However the only problem I had with it before was that IMHO it activated the lights too quickly. I want to know if there is any way to slow down how soon it activates the lights. I would like to stretch it to about 10 seconds if at all possible. Thanks for any help.

The 545T Nite Lite system,  I always liked them, and have them on my own vehicles.  I've never experimented with changing any values on the system though.  Alwayd seemed to work fine for me.   Except for like a manual override switch.

want to bump this and see if anyone has any ideas for how to do this.2013 Chevy Impala LTZ
