The Saga of my Denali D2D LED Lights
When riding at night – being able to actually, you know, see? …is a pretty big plus. Since I have the Void Rally coming up where I will be spending a large amount of time riding in the dark, it seemed like a no brainer to get some extra illumination. So a few weeks ago, I got a set of Denali D2D LED lights for my Tiger.
Wiring the lights up required pretty much taking all of the plastic bits off of the bike and running the wiring under the tank and into the block under the seat. So, doing all of that neatly required a couple hours. It wasn’t a hard job, it just took some time because we were doing it for the first time. When I say “we”, I mean Kenny. My job was to be annoying and hold the gas tank up, which I did flawlessly if I do say so myself.
Imagine our surprise to find that at the final stage of installation, screwing the second lamp onto it’s pivoting bracket – that the screw wouldn’t bite. It just spun in the bracket. What the heck? The light seemed to have a machining defect that wouldn’t allow it to slide fully into position and sit flush against the bracket, making the screw too short. Great.
We sent an email to Twisted Throttle where we’d bought the lights and explained what was happening. They requested some pictures of the light showing the issue, which we sent and they sent us an RA for the single lamp. They said it was no problem, apologized for the trouble and let us know they’d send us a new single light.
After checking to see that they received our returned light, there it was: Oooooh, sorry. Backordered. The availability showed a date of mid-October. That wouldn’t help me on my rally but there was no point in freaking out. What can you do? Stuff gets backordered.
Kenny, my angel, decided to take one for the team and buy a second set of lights to put on his Tiger. The thought being, he would order a set so I didn’t have to be crippled by my backordered light. He would give me one lamp out of his new set and then take my replacement when it came.
Three days later, Kenny’s set of lights showed up. He took one of his new lamps out and installed it on my bike. Angels sang, birds tweeted, all was right in the world. Mostly.
A few days after that – my original replacement light actually showed up, too. Kenny had already gone through the process of setting up the wiring on his bike and put the bracket in place so that when the replacement light came it would be a basic plug in with all of the leg work already done.
You Have Got To Be Kidding
The replacement light would not slide fully into the bracket and the screw wouldn’t bite.
I think it might have taken every once of self control that Kenny had for him not to go all Hulk Smash! and splinter the light on the garage floor.
Instead he did a little grinding, a little drilling so that it would attach. A “light tap” for its high tolerances just didn’t cut it.
Fine, whatever. We now have two sets of working lights.
Both of which apparently have an intermittent slight flicker in one lamp when running on the low beam. Oh, COME ON!
What would cause the lamps to flicker? Is it worth sending the lamp back again? For $350+ bucks you’d think I wouldn’t have to even ask this question.
Kenny took a video of his light flickering while the bike was idling in our garage and sent it to Twisted Throttle. They sent him another RMA.
We’ll see if his replacement light has any issues.
What a pain.
Based on Ken’s questions in the comments – just a little recap in case anyone has suggestions:
- Both of our Tigers have intermittently flickering lights.
- 1 Tiger has 2 lights that flicker, the other, only 1.
- Flickering occurs at idle when the bikes are running.
- Flickering occurs at varying RPMs while riding.
- Flickering only occurs on the ‘low” or 40% beam, high beam does not flicker.
- Flickering does not occur when the key is switched on but the bike is not running.
- TT suggests a “light tap” will allow the screw to seat… eh, that wasn’t the case for us.
To recap, my Tiger has 2 light pods that pulse or flicker intermittently. Kenny’s Tiger has only 1 light that flickers, the other light is fine.
Tonight, Kenny took his 1 good, non-flickering light and put it on my bike. It did not flash on my bike either. The “good light” operates as it should, no matter where it is plugged in, on either bike.
My bike with Kenny’s ‘good light’ and one of my original flickering lights on the low beam:
Okay, so… A couple phone calls and emails back to the guys at Twisted Throttle~
The first tech suggested that they would sending us a newer version of the harness, which apparently uses a plastic box instead of metal and has new innards. He thought that might help kill the issue. The suggestion was that the metal box might be causing some problems.
After talking with the tech, Kenny took a look at our bikes once more and found that his Tiger already had that updated plastic box harness, my Tiger did not.
Another follow up call with another tech letting them know about the harnesses. During this call, the tech mentioned that the Tiger was known to have a dirty power issue causing problems with these lights. Uh, what?
If there was some knowledge of a “known issue” why wasn’t it mentioned right out of the gate? Or noted on the website? Or why would there be RMAs for parts to be returned or someone saying they’d send new wiring harnesses? If it is a known issue – surely there would be an appropriate place to mention a workaround on the website or on one of the previous calls or emails, no?
So, yesterday Kenny did a little testing. The light only flickered on low beam when the high beam wire to the controller was wired in. If the highbeam wire was not wired in, the light would not flicker on low beam.
Wiring a relay off the headlight to the high beam power on the controller. That’s it. A hack fix putting a relay in front of a relay (in the controller).
Were you hoping for something more complicated?
Let There be Light!
Tonight, my Tiger’s Denali D2D lights shined on low beam with no flicker. I could have wept. It was the greatest day of my life, since last time.
So, through all of this, the folks at Twisted Throttle didn’t give us a hard time, they were pleasant, tried to be helpful and they were really good with being open to returning things. The techs took time to talk things through with us when we called.
When all is said and done my only complaint is really - if there was some knowledge of a known issue with the Tiger, just include what needs to be done at the time of install somewhere. It would have saved a shitload of time and troubleshooting.
