Toogle switch tripping after 10 seconds after hooking up new Halogen lights

Very important. Relays are rated for intermittent duty. A DC lamp is continuous. So make sure that your relay(s) rating is about three times the value of the collective lamp current draw.
A switch is typically rated for no more than 15 amps continuous. Typical halogens draw 5 amps each.
You would be shocked at how hot an undersized wiring harness can get inside the tower. I would recommend having two independent circuits, one front, one rear, and no less than 14-gauge conductors for both.
Poor crimp connections are another source of intense heat.
Then, do not overlook the gauge of harness that supplies the fuse and switching. The helm bus is often inadequate. Best to have a direct line to the battery.
