Denali D4 Flood & Spot Hybrid LED Lighting Kit
Simply put; the Denali D4 is a beast. It is the most powerful and most versatile light packing the punch of four DM lights in one rugged housing. The four LED pod is equipped with two 60° elliptical flood lenses and two 10° spot beam lenses to create the ultimate hybrid beam pattern; a super wide close-range flood and single piercing spot beam. Consuming only 20 watts of power per lamp, the Denali D4 lights throw a blazing beam of light 550 feet down the road in front of you. That’s over 3 times further (and way wider) than your typical motorcycle high beam.
- Pod Size: 3.9" square x 2.5" long
- Beam Distance: 550ft
- Light output: 1940 lumens per lamp, 3880 total lumens
- Power Draw: 20watts per lamp (3amp total draw)
- Intensity: Single
- Beam Angle: 10° lenses and 60° elliptical lenses
- Waterproof: IP-68 (full immersion at 6.6ft for 60 minutes)
- Bike specific Denali Auxiliary Light Mount available (sold separately)
- 2 LED pods
- Wiring harness
- Standard mounting hardware

Reviews & Questions
The spot and flood combination provides wide coverage and there is no issue with outdriving the lights. As with all LED's the white light provides clarity and in my opinion reduced fatigue and increased concentration span.
Driving at night on asphalt was not an issue and I also had the opportunity to use them in severe thunderstorm and they worked well making it easy to see "through" the rain without the normal glare issues.
One needs to manage the light carefully with oncoming traffic and I had a feeling they were blinding a few cars at quite a distance away....
It was also fun to bright back at some idiot truckers who seem to have fun with switching their brights on before they pass you.
Installation was easy and integration of the system to the main beam of the bike was simple and elegant. Still having the override switch to run with just the standard bike lights is useful in normal road conditions.
I had the bike down many times on my CD trip and the lights were berried in mud and even some impact with rocks, the robust bracketry and housing design ensured no damage to the lights or functionality and I was able to just bend the brackets back in place and get on with it. Will need to fill in some paint work on the brackets to stop them from rusting.
These are pricey!! But I would recommend them to anyone with a need to have wide coverage close as well as spotting the distance! It is one of those investments you will be happy you made when you get in a situation where you really need them!
I purchased the mount for the water cooled GS, and the installation went relatively quickly and easily. The only challenging part for me (and this really has nothing to do with the lights at all) was finding a good spot to mount the relay. The kit pretty much included everything I needed to do a professional-looking, secure installation. I do have one thing I'd put on my wish list, and I talked with a Twisted Throttle rep about it. For the R1200GSW (which I have to think represents a pretty sizable chunk of the D4 market), you cannot control the lights with the bike's high beam switch because the high beams aren't voltage controlled. They run off a CanBus, but the relay needs an analog input from either a conventional high beam switch, or you need to use the dedicated switch that comes with the D4s. Incidentally, the switch mounting plate isn't included, so plan on ordering one when you order the lights. The left grip on a fully equipped GS is a busy place already (see photo below) and I couldn't find a likely mounting spot that wouldn't interfere with other switches. The kit includes a longer bolt and spacers meant to replace one of the rear view mirror/brake reservoir bolts. Even the longest is slightly too short to clear the switch plate on the right grip, so I have it angled slightly down (photo below). It isn't awful, but it means I have to move my throttle hand somewhat awkwardly to activate the lights. I haven't found a longer bolt with the right threading yet, but will easily fix the problem when I do. This isn't a huge deal, but I have to dock a star because of it. This wouldn't be difficult for Twisted Throttle to create a model-specific kit for, but the ultimate fix would be for them to engineer a harness that allows using the bike's high beam to control the D4s. Take note that if you have a "normal" voltage-controlled high beam, the D4 relay can be easily wired in and activated whenever you turn on the high beams.
So, how do they work? Um...WOW! I bought these lights after riding Rt. 33 from Virginia into West Virginia around 10 P.M. one fine summer night. The GS has a phenomenal LED headlight, but that doesn't help you see into the turns since the light stays pointed straight ahead. Hairpin turns on mountain roads in pitch black darkness aren't my idea of a great time. The D4s greatly solve the problem with their bright, wide dispersion beams. They simply turn night nearly into day. They don't reach quite as far straight ahead as the stock LED headlight, but that's not a knock on the D4. They aren't intended for that, but would easily out distance the headlights of every bike I've owned prior to my current ride. If you don't have an LED headlight, I absolutely guaranty the D4 will be brighter and throw the light farther than your headlight. The beam width takes the mystery out of turns at night, so they do exactly what I wanted them to do. One last thing; I really DON'T recommend these as daytime running lights. They are too bright for that.
All told, the Denali D4 is a fantastic product. The only knock I have on them is one specific to my make/model of bike, and not on the lights themselves. I highly recommend these lights without hesitation.
At night, these light up dark roads like the sun was still out. No one can believe how far they throw light and how wide the beam goes as well.
The only thing I would change is to give them two brightness settings so that I can run them when I'm behind other cars.
However, no one has "flashed" me yet. Also, when at a traffic light, or coming up behind a car, I do not see my lights shining in either their side mirrors or their rear view mirror. So, while bright, I am thinking that they are not at a level where they are shining directly on to a mirrored surface on the cars.
Installation was pretty straight forward. The F800 GS is pretty compact where the fake tank is, so there's not a lot of room for wiring. However, with the supplied zip ties, I was able to keep everything tidy.
I also removed additional wiring, by installing a Denali PowerHub2 unit. The Denali D4 wires are too big for the PowerHub2, however, all other electrical farkles are going through the PowerHub2, so that freed some space for me.
