Completed a fun mini-mod as discussed in
this thread
Simply remove the ground wire to the marker lights and connect to the turn signal feed. Now when turn signals are on the markers light up as well. If the markers are on (like with headlights) then they blink alternately with the turn signal.
The benefit of this mod is that the marker housing illuminates more toward the side of the vehicle so the turn signals are more visible to traffic. Also the marker lights come on with the hazards as well.
