Hey guys,

I installed the Integrated (Run-Turn-Brake) Tail Tidy and the Rizoma Club standard turn signals. Looks great and works great with the ignition on. But when I turn on the engine, the brake light won't work, and I get the lamp error. Everything else works fine - even the running tail light - but the brake light will not illuminate when I use the brakes.

I contacted Daedalus, and they sent me a new circuit board, but it still does the same thing. Anybody else with a 2021 have this issue? Maybe the tail tidy isn't compatible with the 2021s?

Possibly the circuit board needs tweaked. Daedalus are normally super-responsive to customers so they should be able to work with you to get around the problem. Unless (of course) a member on here has the solution!

I would check your brake activation micro switch. The switch is located by the rear brake lever, underneath the engine and close to the frame rail. Look for wires going to a micro switch. The micro switch has a silver rectangle metal tang that contacts the foot brake lever. If the metal tang has come dislodged or fallen off your brake lights won't work.

I'll have to look into that. But the brakelight otherwise works fine when the ignition is on. It only malfunctions when the engine is turned on. It has to be something to do with the extra voltage related to the engine turning on.

I've contacted Daedalus, and they're looking into it. Apparently a few others have had the same issue and not exclusively the 2021s. Seems like BMW's electricals have become more finicky according to DAedalus.

Hi, same here on my 2021, everything works fine, but after braking a few times with the engine on, the brake light stops working with a lamp error. Tried plugging a resistance to the brake light only but the same problem happened. Waiting for a new circuit board from Daedalus, they're very reactive; will keep you posted!

I work at a BMW Motorrad dealership and we've already installed a couple of Daedalus on '21 NineT's with no issues though.

Yes. Daedalus has been very responsive. They also sent me a new circuit board with an added resistor. It now works, but the brake light is dimmer. They will be sending me another one with a lower rated resistor. Will update when it comes in.

$500 to be a beta tester =(

Really hard to fault Daedalus on this one. They're standing behind their product by working with the OP. Without long term access to a 2021 bike how do you really expect them to have had this ready anyway?

Hey guys sorry we haven't been super active on the forum of late, a lot going on right now!

Yea the 2021 issue has been a bit frustrating. As far as we can tell what's changed is the bike is now drive by wire, which is good but shouldn't affect our kit. Something I found out last week was BMW apparently has switched back to a single wire Brake / running line, which inherently shouldn't cause any differences as that's how it used to be on the US 2014-2015 bikes.
Part of our kit has a small circuit that brings over lower voltage from the license plate light to the brake light to produce a dimmer running light. We had to do this for all the EU bikes as well as all the 2016+ US bikes as well. That being said, there's protection on the board to prevent extra current from "going back up" the system so it shouldn't matter.

That being said, we found out last week that adding a small resistor in line with the main brake power cable has produced success in keeping the brake lights on. This would make sense as it essentially lowers the voltage going to the brake light. Why this is now the case... I really can't say. We never had an issue with the brake light by itself until now. If this is what it takes, that's an easy fix. A bummer for sure as now there's a number of you guys with 21's having this issue and fixing retroactively isn't ideal.

We're tallying a list of who's effected so far and will be able to get replacement circuits out starting Monday of next week, once our next shipment of circuit boards arrive.

I also am working with an electrical engineer who might be able to build us a more reliable/consistent circuit board. Just waiting on BMW to let us borrow a 20/21 nineT to test on to see what we can do. The resistor fix is easy and works, but something more complete would be ideal

As some of you might know, we've had issues with the 2017+ bikes, especially with the classic kit, paired with the Rizoma Club S or similar external running signals shutting off in a similar fashion. On the plus side of all this, I tested this on a 2020 last week at BMW SF and the bike worked 100% in all configurations which is great, means we might be able to offer this option to everyone again if this resistor fix does the trick.

Stay tuned!

Update on my tail tidy and 2021 9T. Daedalus sent over a new circuit board with a number of clip on resistors (5 ohm, 10 ohm, 15 ohm, and 20 ohm) to try. I believe the initial resistor was rated at 30 ohm, but I noticed that the brake light was dimmer, and it was actually hard to see when the turn signal was flashing.

I tried each resistor, and each one was a tad brighter than the last. The 5 ohm resistor was definitely brighter than the 20 or 30 ohm. So I left it in place. I turned on the engine, and the light still works just fine without shutting off or setting off the error light on the dash.

Daedalus will also send me some even lower rated resistors just to see where the "shutoff" point will be.

I have to say that Daedalus - and especially Ross - have been quite responsive to this whole ordeal, so I've been satisfied with the service. Unfortunately, now the little rubber nipples that keep my seat cowl in place are getting fractured from pulling it off and putting it back on so many times. Otherwise, it's a great looking tail tidy!

Good to know, thanks for the feedback, will update you guys as well when the new circuit board comes in. Cheers!

Following....interested in a kit for my 2021!

 

[Ronsef]

ordered my tail tidy for 21 few weeks ago. Excited for when it comes in. hopefully soon!

Have the issues been sorted?

 

[Simon Buster]

I have a 5 ohm resistor on there and it seems to work fine. They said they were going to send me even lower rated resistors to see at what point it shuts off again, but I didn't get anything.

no idea. i hope so, i havent recieved any update on my order yet. Im hoping it is all sorted and ready to go.

Hi, thanks for the above info. I mounted classic daedalus on my 2021 ninet yesterday and it has the same problem with the break light and the dash warning. How do you change resistor or do I need to get a new circuit board to be able to do that?

 

[Ronsef]

did you just receive yours?

You would need to change the circuit board in order to get that. Does that light remain on while you are riding? I believe your kit already has a resistor installed as we're starting to send out resistor equipped boards to all our new '21 owners. The inconsistency between bikes is a bit of a head scratcher... We did just start working on a new board with an electrical design company who will have more insight into this problem. At the very least we can make it easier to install resistors for this issue.

thanks for the update on this! totally excited and hope everything will come out ok =D
