I saw a few pictures of 4th gen maximas that had the blinkers on constantly with the headlights. Does anyone know how to do this mod??

 

Yes, I have those. Go to Pep Boys, or Autozone and get two dual filament sockets (for an 1157 bulb). Then buy a pack of 1157 bulbs.

To wire it: The sockets come with one [positive + red], and two [grounds - black]. Splice the red wire into the green wire of your turn signal, then splice a black wire into the black wire of your turn signal. With the other black wire on the socket, your going to splice it into the black wire on the sidemarker.

If I've confused you please pm me and I'll explain it further.
