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. CNC is machined from solid aluminum, then given a perfect brushed finish, and finally anodized in black to provide a thick and incredibly durable coating. The internal circuit board contains a 32-bit RISC microcontroller that carefully controls the LEDs for maximum brightness and performance, ensuring the X-Arc signals are blindingly bright.

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.


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

High Tech Speed buys USA-made aluminum and turn and mill it to precise tolerances on their 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 High Tech Speed's 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 are 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 final test and programmed with a default setting prior to being cleaned, wire-tied, and placed in protective bags before final packaging.


Companies like to use terms like "super bright" and "latest generation LEDs" or talk about the number of LEDs 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 turn signal.

The pictures in the listing are taken with the same camera settings with the signals mounted the same distance (12in/30cm) from the backdrop.
