2013FX4

Hey guys and gals, long time listener, first time caller. I have a 2013 FX4 and i recently took my stock side view mirrors with power, heated, signals etc and installed puddle lights. I wired into the blinker as it was the closest powered wires and I didn’t want them constantly on. I’m ok with the extra light flashing when I use my signals.

Ok ok my question is, is there any way to increase the time that they are lit when I unlock my truck? Surely there is a way to have the courtesy blinkers stay on for more than the two seconds that they do currently. I’d love to hear your thoughts and I appreciate the time!
