    IF Series Wiring An IF series DuoBeam™ has a dedicated ground wire and one or more +power wires routed to the modules. The black ground wire should be connected directly to the battery. The amp ratings for each module type are detailed in the specifications secion of this installation guide.
  • Page 6 IF Series Flash Pattern Selection The DuoBeam can be populated with one of two different module types - PriZm™ or Torus™. For PriZm™ (8 or 12 LED) style modules, the flash pattern on each individual module can be cycled to the next flash pattern (shown in TABLE 1) by briefly shorting together the 2 short pads with a wire or the blade of a screwdriver as shown in FIGURE 5.
  • Page 7 For Torus™ (6 or 9 LED) style modules, the flash pattern on each individual module can be cycled to the next flash pattern (shown in Table 2) by momentarily shorting together the JP1 pins with a wire or the blade of a screwdriver as shown in FIGURE 6. The module will reset to the default flash pattern when the JP1 pins are shorted together for 5 seconds or more.
  • Page 8 TR Series Wiring A TR series DuoBeam™ has a single cable with 7 colored wires. A dedicated ground wire, a dedicated power wire and five colored control wires which run through the main driver board. The 16 AWG black ground wire should be connected directly to the battery. The 16 AWG red power wire requires a constant 10 to 16V(+) power source with a customer supplied in line 15A fuse.
