LED Taillight
Hi all, trying to fix the LED taillight on my 2007 Norge.

2 of the 16 in total LED's are running very dim, during normal light and when braking. I did manage to get the housing open: hot air gun on the ABS black cover and some intelligent force.

My first step is to replace the 2 LED's before I dive in potential circuit board issue's.

I'm looking for some specifications of the LED's, anybody with experience in this particular repair?
Output in mcd and voltage is where I have questions on.

What I know sofar: circuit board is manufactured by CMT (Italy), the LED's are SMD type with PLCC4 housing

Regards,

What you are asking, doesn’t exist!

This information is not standard nor published by Moto Guzzi.

In fact, no manufacturer would have this type of info available.

Think about it, what you are trying to do.

You are trying to rebuild a finished and sealed, unserviceable component.

You’re on your own with this one my friend. Guaranteed.
 
I have exactly the same issue but not looked into it yet. Alternativey but a broken one and swap the LEDs over.... maybe chepaer if you ahve the sealed intit dismantled already.
 
No, just a bit further away in the one that started the industrial rev olution (allegedly). Mind you if someon has a broken one and can take a few od the LEDs off carefully I would appreciate them being sentover at cost of course... Not much chance of that I think though. And its a sealed unit and there are places that repair them I know as Ive seen it on Car renovation programs.
 
I bought a pack of 10 leds off ebay to repair mine, it's the moisture that gets in to the light that causes the problem. I'll try and dig out the type of led I got

Hi Scott, just for the challenge. If it doesn’t work I’ll get myself a replacement.

12v red LED, possibly 2 voltage/brightness levels or a twin LED with 2 inputs (Light and brake activated) one output... should be easy to find and they wil be using off the shelf parts Im sure as Guzzi dont design LEDs. Lets see Briand can find a spec. Other than that ill strip the rear end and dismantle the unit. I have seen then with the back taken off so shouldnt be that hard, or is it even a real sealed unit?

Yes, it’s sealed. However at this age, the seal is no longer intact. Water intrusion is an enemy then.

When I got my 1200 Sport, I seperated the lens from the body of the rear brake light, and then carefully re-epoxied it back together again to make a new closed seal.

I ended up drilling a few small air relief holes in the back side which is protected by the motorcycle chassis to allow air moisture condensation to evaporate.
 
Of course if it is water 'damage', and the 2 on my light are towards the top, then it could just be deposits shorting out the LED or part of the circuit (I assume ita a board) rather than a failed LED and they ususlly have millions+ operational lifetimes.
When the garage is warmer Ill check mine out.
 
OK the closest one I can get is the KingBright 604-AA3528SURSK I think, any isead as I cant find anything clost with the 4 foot packeage anymore?
 
Can you post photos of the PCB? It would help to know if the current limiting is done resistively on the PC board itself or if somehow a different module on the bike is responsible for that.

If the current limiting is done on the PC board, I would suggest getting a cheap 3A adjustable bench supply and ordering an assortment of LEDs from Mouser with the appropriate package, and double the brightness with each different part number. Presuming these are all surface mount parts, you can just touch each one to the PCB hooked up to a bench supply to find one that's about as bright as the others, then you'll know what you need.
