In brief. DENALI Electronics builds a modular motorcycle lighting system: the light, wiring, and controller are purchased separately and combined. The range available from Endurrad includes the DL DataDim series (DL-2, DL-4, DL-6, DL-9), the D series (D2, D3, D4, D7, DM, DR1), the S series (S4), and the DialDim and CANsmart controllers.
The thing to know before looking at prices: lights in the D series are sold individually and without wiring. The DL series is available both individually and in pairs. A price that seems low is often the cost of half the system.
What is homologated: DENALI lights are certified as auxiliary high-beam lights (ECE R112 or R149 driving beam). They do not replace or supplement the low beam: they switch on with the motorcycle's original high beam.
What is the DENALI system
DENALI Electronics is a US manufacturer of motorcycle lighting and components. What distinguishes it is not a single light, but the fact that all its products communicate with one another through a proprietary management protocol.
The system consists of three levels. The light, available in many sizes and power ratings. The wiring, which can be universal with a handlebar switch or specific to the motorcycle model. The controller, which is the most interesting part: DialDim in the universal version, or CANsmart when the motorcycle has a compatible data bus.
The technology that ties the system together is called DataDim. It uses three-wire wiring with a dedicated intensity-control line: this allows the light to change brightness automatically in response to the motorcycle's original high-beam control, without additional switches. This is why it makes sense to stay within the ecosystem once you have chosen it.
The range available from Endurrad
DL DataDim Series
This is the newest line and the one with the most complete technical documentation. The entire series states ECE R149 driving beam certification, IP68 and IP69K protection ratings, a 6000 K color temperature, 9-32 V DC voltage, and compliance with EMC R10, CISPR 25, CE and UKCA. DrySeal construction robotically seals the lens and uses internal potting at the cable entry, which is where these products really fail. The lenses are not interchangeable: the beam is chosen when purchasing.
| Model | Pod dimensions | LEDs | Watts/light | Lumens/light | Lumens/pair | Beam | Price per unit / pair |
|---|---|---|---|---|---|---|---|
| DL-2 | 3 x 2 inches | 2 | 16 W | 1.700 | 3.400 | Visibility, wide flood | 106,00 € / 203,00 € |
| DL-4 | 3 x 3 inches | 4 | 32 W | 3.400 | 6.800 | Hybrid | 138,00 € / 267,00 € |
| DL-6 | 4.5 x 3 inches | 6 | 48 W | 5.100 | 10.200 | Hybrid | 187,00 € / 363,00 € |
| DL-9 | 4.5 x 4.5 inches | 9 | 72 W | 7.650 | 15.300 | Hybrid, 421 m per light | 235,00 € / 459,00 € |
The DL-2 is the only one in the series with a visibility-type beam: a wide flood at night, designed to appear as bright as possible to other drivers during the day. It is the choice for commuting or as the lower pair in a two-level setup. The DL-9 is the most powerful DENALI listed on Endurrad, with a claimed range of 560 meters as a pair, and it is also the largest: it only looks at home on adventure maxi bikes.
D series and S series
These are the established lines, sold as individual units. On the D2, D3, D4 and DM, the TriOptic system includes one mounted spot lens and one included flood lens, so with a pair you can configure spot+spot, flood+flood, or one of each type. This is flexibility the DL series does not offer.
| Model | Lumens/pair | Watts | Beam | IP | Certification | Price (per unit) |
|---|---|---|---|---|---|---|
| DM | 2.190 | n/a | Spot + TriOptic flood | n/a | E-Mark on flood lens | 165,00 € |
| S4 | 6.132 | n/a | Hybrid, sealed lens | n/a | Not declared | 171,00 € |
| D2 | 2.190 | n/a | Spot 160 m / flood 50 m | n/a | E-Mark on flood lens | 219,00 € |
| D3 fog light | 5.600 | 40 W | Fog light | IP67 | To be confirmed | 235,00 € |
| DR1 | n/a | n/a | Narrow spot, approximately 10 degrees | IP68 | Not declared | 240,00 € |
| D3 | 4.200 | 36 W | Spot or hybrid, lenses included | IP67 | SAE J581 + ECE R112 | 248,00 € |
| D4 | 8.760 | n/a | Hybrid, 2 flood + 2 spot | n/a | E-Mark on spot lens | 291,00 € |
| D7 | 7.665 | 70 W | Full spot, over 366 m | IP67 | E-Mark on spot lens | 395,00 € |
The D3 deserves a note: it is the only one in the range with documented dual certification, an SAE/DOT J581 and ECE R112 hybrid lens, and an ECE-only spot lens because it is too powerful for US regulations. Both lenses are included.
DialDim and CANsmart: the part that makes the difference
Buying DENALI lights without the controller means using half the product. The controller unlocks the features that make you choose this brand.
The universal DialDim, €331.00, lets you independently switch on and adjust two groups of lights from a single knob. It adds synchronization with the original high beam, a horn-linked strobe, automatic turn-signal shutdown, an adjustable electronic fuse, and a battery voltmeter function.
The CANsmart is the motorcycle-specific version for bikes with a compatible data bus, typically BMW: it connects to the diagnostic socket and lets you control the lights using the original handlebar buttons, without cutting a single wire.
Endurrad also offers complete packages for BMW GS models that include lights, dedicated mounts, and a CANsmart under a single product code: from €1,006.00 for the R 1250 GS with D4 to €1,585.00 for the R 1300 GS Adventure with D7 PRO. The D7 PRO is available only in these kits: seven 14 W Cree XML3 LEDs per pod, 98 W power consumption, 11,900 raw lumens per pod, IP68 and IP69K, an E-Mark ECE R112-approved spot lens, with a dual independent circuit that lets you use the central optic as a DRL or as a full-power flood.
When DENALI is the right choice, and when it is not
DENALI makes sense if you are building a layered system with multiple pairs of lights serving different functions, want interchangeable lenses to change the beam according to the season, have or want a CANsmart, or need the highest protection rating available with the DL series.
DENALI is not the right choice if you are looking for an approved low beam. This is the brand’s structural limitation in the European context: its lights are certified as auxiliary high beams, so they work in pairs with the original high beam and switch off with it. If your problem is getting more useful light even when encountering oncoming traffic, the answer is a light with an ECE R149-approved low beam, such as the L series from LOBOO.
It is not the right choice if budget is your main constraint and you want a complete system right away: two D7s plus wiring cost more than €800, while an approved pair of LOBOO lights with wiring included starts at €261.00.
