X2 Model-Specific kits are plug-and-play. No cutting or splicing of wires required. The back of X2 is customized with the same connector your model bike uses. X2 is compact and self-contained with no pieces protruding in the back or light-leaks. There is an integrated cable guide to help keep the lines from rubbing. The model-specific instructions were written with your model in mind. Some models require high-output stator, as noted. Halogen lights can be used on most machines with a stock light and AC or DC power. Most model-specific X2 kits come with a custom wire harness that includes a switch. The switch is set to utilize your model's electrical system to the best of its ability; some models can run both lights at the same time, but some can only run the high or low beam. If your bike did not come stock with a switch, one is included in the model-specific kit; either a 2- or 3-position switch. For most models, when the switch is set to low the upper 2 inch lamp's spot beam turns on to illuminate the area ahead (the 4 inch flood lamp is more blinding because of its spread.) On high both lamps ignite to illuminate both near and distant terrain. Halogen Dual Sport lights offer a clipped beam that is less offensive to oncoming drivers (its lamps meet DOT requirements for on-road use.) Dual Sport clipped beams are aimed closer to the road that off-road versions; they are less likely to blind oncoming traffic. Fits: KTM EXC/MXC/XC-W/XCF-W/EXC-R 2000-2013 (off-road models with factory lighting, carbureted models only); Husaberg TE 250/300 2011-2013 (for use with stock or Trail Tech high output electrical system).
