The DENALI D4 TriOptic™ LED Light kit is one of the most powerful LED lighting systems on the market today but draws only 6.6A at full power.
The system comprises two tough metal housings equipped with eight high-power LEDs. The housings are made from
aluminium with a black powder-coated finish and have cooling fins cast into the body for maximum heat
dissipation.

Light Coverage
The kit includes two different pairs of lenses ("True-Hybrid"™ and Spot) to provide three
types of light coverage.
1 - "True-Hybrid"™ Beam Pattern
In this configuration, each housing uses the same "True-Hybrid™" lens plates: the two upper lenses are spots
and the two lower lenses are floods. The housings are supplied from the factory with these lenses already
fitted as this is the most common configuration.
This provides a 172m (560') forward beam with 42m (140') wide side-coverage.

2 - Spot Beam Pattern
Each housing is fitted with the same Spot lens plates. Each of the four lenses are spots. The spot lens plates
are included in the kit but are not fitted by default.
This provides a 243m (800') forward beam with 33m (110') wide side-coverage.

3 - Spot-Hybrid Beam Pattern
Each housing is fitted with a different lens plate: one with a "True-Hybrid"™ and the other with a Spot lens.
This provides a 190m (625') forward beam with 42m (140') wide side-coverage.

How are the lights controlled?
The lights are controlled by a high-quality, waterproof On/Off switch, included in the kit.
It is also possible to use the lights at half intensity and/or controlled by the vehicle's original main-beam
switch by using additional accessories (not included in the kit): see the Optional
Upgrades section below.
Installation
Due the size of the D4 housings, they are normally fitted to crash bars or other types of robust bike
protection systems.

Also Available (optional) Amber Lens Plates
Blue light is reflected by fog/water vapour/rain. The DENALI Amber Lens Plates
filter out the blue component from the LED white light and so improve visibility in fog and rain.
This kit includes two pairs of lenses:
"True-Hybrid"™ lenses (two upper spot lenses and two lower flood-style) x 2
"Spot" (four spot lenses) x 2.
The amber lenses for the D4 lights are available
here.
DENALI 2.0 Lights - Common Characteristics
High Power LEDs - HiDrive™
The LEDs used in all DENALI 2.0 systems are the latest generation "Hi-Intensity" LEDs from Cree.
Compared to the DENALI 1.0 series, these produce 20% more light (lumens) for the same low current consumption.
Advanced Thermal Management - LiveActive™
LEDs last longer and output more light when they are kept cool. The DENALI 2.0 lights have advanced software control "LiveActive"™ integrated into the LEDs and external oversize heatsinks cast into the housing to maximise the efficiency minute-by-minute and ensure the longest lifetime.
Multi-Beam Lens system - TriOptic™
All kits include two spot lenses and two flood lenses to allow a choice of three lighting patterns. Use two spot lenses for the maximum forward reach, two elliptical floods for maximum side spread, or one of each for a combined effect.
In addition to providing three beam options in one kit, the second set of spot-only lenses are CE-certified. This ensures you can stay street-legal on-road while maintaining the option for maximum distance off-road.
Fully Waterproof Construction - DrySeal™
The seals between the components of the housings are moulded silicon and the cable entry points are potted in epoxy to ensure the housings are 100% watertight even when submerged. The control switches (On/Off and Off/Low/High) are also 100% waterproof.
Corrosion-Proof Bezels - Impact PC™
The front bezels always bear the brunt of stone damage and so the coated aluminium of the main housing is not always an appropriate material. The housing bezels are moulded in 100% polycarbonate (DR2, DM and DR1 only/not D4) for the best possible resistance to stone damage, providing a tough surface that does not rust or fade with the sun.
Chromed Reflectors
The internal LED holders are plated in high reflective chrome to focus all the generated light forward and to better match the bike's original headlights
Low-profile mounts and stainless-steel fixings
The hinged mounts are designed to reduce the installed profile to the minimum possible while maintaining high strength. All screws and nuts are manufactured in stainless-steel.
Waterproof Switch – "DrySeal"™
All DENALI switches are completely waterproof to ensure a long lifetime in harsh, outdoor conditions. The switches can be mounted on a flat surface or a handlebar (22mm/25mm).
HotSwap™ Wiring Harness
The cabling uses high-quality waterproof components and allows a simple upgrade to dual intensity LEDs by the use of the DataDim™ Controller Relay (available here).
Optional Upgrades
DataDim™ Controller
This relay allows the lights to be switched between Off/Low Intensity/High Intensity.
The lights are switched Off/On by the standard switch included in this kit.
The Low/High intensity is controlled by the original main beam switch of the motorcycle via a connection to the original main beam circuit.
The DataDim™ controller relay (available here) replaces the Single-Intensity relay that is included in the kit.
DataDim™ Controller + Hi/Low/Off Switch
This option provides full control of the lights independently of the main beam control.
In some motorcycles it is impossible to use the main beam control and so this manually-operated switch is required.
This option replaces the standard Single-Intensity relay with a DataDim relay (available here) and replaces the standard Off/On switch with the Off/Low/High switch (available here).
Switch Eliminator
This allows the lights to automatically switch on with the ignition circuit, so are always on when riding. This option replaces the standard On/Off switch and is available here.
Harness Extension
This cable extends the length of the standard lighting harness by 61cm (24") and features the same high-quality waterproof connectors as the original DENALI cables. It is available here.
Y-Splitter Kit
If you wish to add one or two more lights to your existing DENALI system, the "Y" splitter kit makes that very easy. It is available here.
Auxiliary LED Brake light
The B6 LED auxiliary brake light is a great safety addition to your existing brake light to wake up those cage-drivers! The unit comprises six 0.5W LEDs in a very compact, low-profile housing and is available here.

DENALI Lights - EU Compliance
Please note there is NO EU category for "auxiliary lights". Additional front-facing lights can only be designated as "fog lights" or "headlight" replacements.
"Headlight" replacement means that one additional light my be used with the existing main beam light but two lights may NOT be used with the existing main beam light: in this case the function of the original main beam should be anulled.
DENALI lights were originally designed for the USA market and subsequently marketed to the rest of the world, including the EU.
Consequently the certification of the lights in line with EU classifications was done later.
EU compliance (E-Mark approval/homologation) documentation can be downloaded from the DENALI website here.
S4 Auxiliary Lights
Not certified.
DM Auxiliary Lights
The DMs are not sufficiently powerful to be classed as replacements for the main headlamp and are too powerful to be classed as fog lamps, so were certified as “AR-Reversing Lamps” in order to have some certification, rather than none at all.
D2 Auxiliary Lights
The DMs are not sufficiently powerful to be classed as replacements for the main headlamp and are too powerful to be classed as fog lamps, so were certified as “AR-Reversing Lamps” in order to have some certification, rather than none at all.
DR1 Auxiliary Lights
Certified as a R-main beam headlamp replacement.
D4 Auxiliary Lights
Certified as a R-main beam headlamp replacement.
D7 Auxiliary Lights
Certified as a R-main beam headlamp replacement.
