Electronics » Dynamic Motorrad LED turn signal bulb problems.

Just curious. I know more than one forum member has replaced there turn signal bulbs with LEDs from Dynamic Motorrad. Has anyone else had any issues with them? Riding home yesterday I got the yellow warning symbol and a bulb out error on the dash. I checked all the lights. The right signals seemed fine. The left side seemed to be flashing about twice as rapidly as the right side. It also looked like a couple of the LED chips in one of the bulbs weren't lighting. On this morning's ride in, everything seemed fine. I've emailed them since they're supposed to be lifetime bulbs to find out how to proceed. Has anyone else who's using these bulbs had an issue?

I will post follow ups about resolving this issue.

I have them front and rear and all good so far 🤞🏻

No issues here. You can contact the company, but my guess is that the one flashing too fast has a burnt out component...this tricks the CANbus into thinking something is wrong...well, I guess something IS wrong.

I thought I'd follow up. I emailed Dynamic Motarrad and had an answer in 24 hours. Mail us the bad bulb and as soon as we get it, we'll mail you a replacement. That's about what I expected. The problem is proving to be an intermittent one. I did it Tuesday evening and hasn't done it since. It happened right before I stopped at a store on the way home. I had to make several stops. Each time I'd restart the bike, the error was clear. Switch on the turn signal and it was back. It hasn't done it since Tuesday night so I guess I'll have to see if it happens again. I have not reason to believe they wouldn't make it good. I just don't want to send them a bulb until I know it's the one causing the problem.

We have three sets of their LED turn signal bulbs. We're presently using two sets. We even remove and replace them when we get new bikes. Have had ours without issue since 2016.

Last night, on the way home, it happened again. It seems to be tied to how long the bulb is flashing. If I signal a lane change or something brief, it doesn't do it. Yesterday on the way home, I stopped to run a few errands in an area with a lot of lights. I would have to sit a a light for half a minute to a minute. Then I got the error on the dash. I guess something in the bulb warms up with use and gets funky. When the bulb cools down, if you switch off the ignition, the error clears. The bulb will then work for short bursts. I spent some time diagnosing it last night. It's just one bulb. If you turn the signal on and let it flash for a bit the error lights on the dash, the bulb starts flashing rapidly, and seems to cycle around the bulb in a circular fashion. If you switch the bike off and let the bulb cool down, the error clears and the bulb works correctly again.

Now that I know which one it is, I'll mail it to them over the weekend for a replacement. I suppose like anything electronic, no matter how good or reliable, some do go bad. I'd still highly recommend them. I used the stock bulbs to switch out and isolate the bad bulb. The stock bulbs are nowhere near as bright as the LEDs.

Good you got it more isolated. Very positive response from MFG. hopefully they make good on it, making their product even better.

I mailed it off yesterday. $16 for out of country postage. Ouch! I have a tracking number so I'll know when they get it. If they are a quick with the replacement as they were returning my email, this should be quick.

The bulb arrived at Dynamic Motorrad yesterday. 10 days to mail it to them, including clearing customs. We'll see how long it will be before I have the replacement.

Dave,

Did you get your replacement? One of mine just died. Purchased 22 March 2021

I have three sets, two purchased in 2016 and one in 2018. Currently have two sets in two bikes. Never had a problem.

It took them a while to send the replacement but they did send one. More than one, in fact. They sent two of them. I think I emailed them for an update after about a month. I know from my tracking information it took quite a while to clear customs and get to them. Looking through my email records, I sent the bulb to them May 14th. I don't know exactly when the replacement finally arrived as we were on vacation but it was some time between June 23rd and July 2nd. You may need to pester them or maybe I was just unlucky. The response to my first email is below and it has the return information. Good luck.

For a warranty replacement, please mail the faulty bulb to:

Dynamic Motorrad
105 Consumers Drive,
Whitby, Ontario
Canada
L1N 1C4

One we receive the bulb we can ship out the replacement right away.

If you have any questions, please do ask and we will be happy to assist.

Dave,

Thanks for the info. I'm awaiting a response to my first email asking for direction on the return/replacement process.

BTW - the initial stage of failure was an intermittent flashing of some of the diodes, sorta of a disco strobe effect. Later, those flashing elements quit working, leave just one or two functioning diodes.

My failure mode was very similar. If I used the signal to change lanes or something brief, the bulb was OK. If I was sitting at a light, longer use, the problem began. It was as though something warmed up with use and then the failure. It was very much like a chaser light or something running around the bulb. The disco strobe is a good way to describe it.
