X-Arc Signals

The brightest signals - really

X-Arc Signals

X-Arc signals set a new standard in brightness and quality. They are only 0.875" in diameter and produce more than 500 lumens of light per side. They are by far the brightest signals you can buy. But don't take our word for it - look below for the proof.

X-Arc signals are CNC machined from solid aluminum, then given a perfect brushed finish, and finally anodized in either clear (silver/satin) or black to provide a thick and incredibly durable coating. The internal circuit board contains a 32-bit RISC microcontroller that carefully controls the LED's for maximum brightness and performance, ensuring the X-Arc signals are blindingly bright.

The X-Arc signals are available in three models. Single color, dual intensity red - ideal for a running light and brake light. Single color, dual intensity yellow - ideal for a running light and turn signal. And dual color (red and yellow), dual intensity - ideal for a running light, brake light and turn signal. The X-Arc light has the internal control circuitry to turn off the brake when the turn signal activates, so no eternal module is required.

X-Arc lights are programmable. There are eight turn signal settings and eleven brake light settings. They come preset to function just as an OEM light would, or you can use the included magnetic switch to change the program to any of the pre-loaded settings.

Installation is easy. X-Arc signals mount using a standard 5/16" bolt, and the wiring passes through the center of the bolt for a clean look. All mounting hardware is included.

Colors and options

X-Arc Signals are available as

  • Dual intensity yellow (high for turn signal and low for running light)
  • Dual intensity red (high for brake light and low for running light)
  • Dual color, dual intensity red/yellow (low intensity red running light, high intensity red brake light, high intensity yellow turn signal)

Size and Fitment

X-Arc signals mount with a standard 5/16" bolt (wires through center). The mounting stud is removable, allowing the X-Arc signal to be flush-mounted directly to the bodywork.

    Programming X-Arc Signals

    X-Arc signals are programmable!

  • For X-Arc RED (single color) signals, the high-intensity red can be programmed with 15 different settings
  • For X-Arc YELLOW (single color) signals, the high-intensity red can be programmed with 9 different settings
  • For X-Arc DUO (dual color) signals, the red (brake) can be programmed with 15 different settings, and the yellow can be programmed with 9 different settings

    First, the X-Arc signals should be installed and wired correctly according to the instructions.
    Second, with the X-Arc signals turned on and active as running lights, place the programming magnet against the signal within the magnet activation area.
    Then, each time the signal is activated, the program will be advanced to the next setting. The setting is saved in permanent memory inside the signal and it will flash with the pre-programmed setting each time.

    To program and X-Arc Yellow signal connected to your turn signals, turn on your bike and place the magnet in the activation area. Turn on your turn signal - each time the signal flashes, the program will advance to the next setting. Once it reaches the last setting, it will go back to the first setting. Once the magnet is removed the setting is saved.

    The process for programming X-Arc Red signals is the same - but if the signals are connected to your brakes, then each time you activate the brake, the program will move to the next setting.

    To program X-Arc Duo signals, place the magnet in the activation area and turn on the bike. Then, each time the brake is activated, the pattern will advance to the next setting. And each time the turn signal is activated, the blinker pattern will advance to the next setting.

    The magnetic activation area is shown below:

    Brightness Comparison

    Companies like to use terms like "super bright" and "latest generation LED's" or talk about the number of LED's their signals use. All that matters is how many lumens of light the signals output and how wide the beam of light is. It's difficult to find lumen ratings and virtually nobody will show you how their signals compare against a factory signal, because almost every aftermarket signal is MUCH dimmer than a basic factory Harley bulb turn signal.

    We want to show that X-Arc lights really are as bright as we say. They put out a lot more light than a factory signal, and in a much wider angle, meaning your bike is MUCH more noticeable than stock, even though the X-Arc signal is one of the smallest signals on the market. The pictures below are taken with the same camera settings with the signals mounted the same distance (12in/30cm) from the backdrop.

    X-Arc lights are truly 100% made in the USA right here in our facility on the North Shore of Boston, Massachusetts.

    We buy USA Made aluminum and turn and mill it to precise tolerances on our in-house CNC mills and lathes. Parts are finished in vibratory tumblers and then given a brushed finish by hand and checked for quality before being anodized either black or clear (satin).

    Meanwhile, American distributors like Mouser, Digikey, Avnet and others deliver electronic components from companies like Texas Instruments, Cree, National Semiconductor, Infineon, Fairchild Semiconductor and others. Circuit boards are loaded with Kester solder paste and run through our Quad/Tyco pick and place machines for assembly.

    The circuit boards are reflow soldered and tested for correct function before being assembled and heat-sinks and adhesives added for water resistance and thermal protection. The almost-finished X-Arc lights have precision-machined lenses installed tightly to ensure water can't penetrate, and are given a last final test and programmed with a default setting prior to being cleaned, wire-tied and placed in protective bags before final packaging.

    After that, they are on their way to you!
