Hi
Still not found the thread to replace some of the LEDs on the 1200 sport or any other LED tail light. Can anyone help as Im sure it will have been done before xx Katie xx

I can't either. I do know they are surface mounted diodes, but not which one exactly. They must have a voltage regulator too as both tail and stop are the same LEDs, running at different voltages. All I can suggest it to find the working voltage of one LED when the stop light is on and see if you can find a red SMD with that forward working voltage. Sorry not to be more helpful.

Hypothesis;
If it’s the same LED at two brightness levels, it’s more likely to be the PWM duty cycle that changes, say 100% for brake lights and 25% for tail. I doubt they’d change the voltage. Not sure that helps find the right LED but might make selection easier. Given some more info (eg package size) it might be possible to get down to a very few candidates by using the filters here. |

What I do know is that when the tail light alone is on, you get a few volts "feedback" on the brake light circuit.

This probably isn't much help but some years ago the LEDs on my Norge tail light began to fail in sequence. The advice from Twiggers was to swop out the entire unit rather than try to replace individual LEDs. I understood the reason to be that, while the LEDs might be cheap, balancing the whole thing so it worked was too difficult and chances were it would just keep on killing them in a row. |

Interesting discussion, Ill take off and split my rear light when its a bit warmer... Should easily be able to tell if its the LED failure or circuit corrosion/tracking issue.

I see you have made some progress, looking at the conversation on Guzzitech. It's looking like the LED is something like this.

I see now so many vehicles with a single led in a row of them failed. As one goes it will prompt others to die and then a WHOLE new unit.
Even vehicles with old school bulbs have been made more difficult to replace. Take Sprinter Vans the previous rear lights were fitted as a unit with 2 spring type clips took under 30 secs to open and swap a bulb clip the unit back in easy cheap fix. Newer ones are the WHOLE lens unit that requires Torx head screws undoing and the driver head needs to be magnetised or the black torx head screws hit the deck and are impossible to see. Once they are undone a 2nd person has to hold the rear door half open and the whole unit has to be hand slapped sideways, try and pull it backwards it breaks the pins and new unit needed. Once the unit is free THEN you can unclip the bulb "rack" and replace the bulb, then the whole unit needs pushing back from the side, whilst someone holds the door THEN you can refit the torx head screws. So 2 guys and 10 mins at least to replace a bulb .... kerrrr ching for the dealerships. These are relatively easy too compared to some vehicles. Maybe this is why soooo many have bulbs out on the roads.

Well just in case anyone else has this problem, it appears the replacement LED is this.

There are supposedly several newer cars that need the front bumper removed just to replace a headlight bulb, so maybe ten minutes doesn`t sound so bad

But we are talking about replacing individual LEDs within the light unit.

Nothing new under the sun is there? Years ago I had a 1974 Rover 2200 (P6). The headlights were sealed beam units. The front steel bumper masked the lamp unit mounting screws. Maybe a sign of the times (1974) rather than of Rover designs. Tony
