The DENALI D4 2.0 TriOptic™ LED light kit with DataDim technology is among the most powerful auxiliary lights on the market thanks to a stingingly strong quartet of LEDs that help you identify trouble as far as 800ft down the road yet still shines brightly to the edges of the road and beyond. Four 10-watt CREE XPL HI LEDs produce a piercing beam of light yet combine to use just 6.6 amps for both lamps.

New with the DENALI 2.0 generation is the industry-leading TriOptic™ lens system. Right out of the box the D4 is fitted with True-Hybrid™ lenses providing a combination of spot and flood patterns in each lamp. This configuration gives you 560' of forward light and 140' of visibility to the side. That’s almost 600' to read a road sign and 140' to see the deer lurking among the bushes. Also in the box are lenses that convert all four LEDs in each lamp to a spot pattern resulting in a tight distance-focused beam brilliant out to 800' while still retaining a 110ft beam width. Want a third option? Fit one of each lens to your D4 pair to get a Spot-Hybrid configuration that offers 625' of maximum distance with a 140' beam width. The spot lenses are E-Marked to be road legal in countries where this is a requirement.

The DENALI D4 housing is only 3.9" square and 2.6" deep and uses cast-in cooling fins to effectively dissipate heat and maximize light output. A durable black powder coated finish and a special Impact PC™ corrosion proof bezel ensures your lights will continue to look great even after repeated stone and debris impacts. Because of its size the D4 is recommended for use with sturdy crash bars or other engine-protection devices or with DENALI’s expanding line of bike-specific mounts.

The D4 2.0 kit uses a just-developed HotSwap™ modular wiring harness that by default causes these single intensity lights to function at full brightness. But if you would like them to operate at both half and full power simply add the dual intensity DataDim™ controller (sold separately). No other changes are required except to replace the original relay with the DataDim™ module and connect one wire to the high-beam circuit. (You can also purchase a three-position switch to manually control light intensity independent of the bike’s high beam.)

DENALI’s previous quad-LED D4 has proven its worth to sport-touring and adventure riders the world over. Now the next-generation DENALI 2.0 D4 is here to take motorcycle illumination to an entirely new level.
