The photos above show a part number on the board (note left & right have different part nums).
You could try and order them at your local dealer - let us know how you get on.

Firstly, congratulations to UK-Nomad on a first class guide to what is clearly cost effective solution to an expensive problem.

After reading his post I undertook this work myself, but was wary of splitting the lens from the rear of the unit. Instead I decided to try and do it by just cutting out the back of the light unit where I imagined the circuit board to be. Using a Dremel I made a couple of trial cuts to work out where the board sat and then cut around it.

Once I'd exposed the board, I cut the blue and brown wires to remove the unit. I'd ordered a pack of 10 x 5mm Ultrabright LED's from eBay (led-essential) for under two quid. I don't work for them but I will say that they were really helpful in identifying the best ones for the job and would recommend them.

I unsoldered and removed the old LED's (including the working one - I wanted a consistent light), and refitted new ones on the original nylon blocks. My soldering skills are poor, but I found if you put the pins through the board and bent them at 45 degrees in opposite directions (see picture) they stayed in place while you solder them. Snipped off the long tails and tested with a 9v battery. The original LED's are white but glow red. Replacements are white and glow white, so I painted them with red acrylic.

Put back in tail light and siliconed all bits together. To be honest, they are slightly dimmer than originals but at least I won't be pulled over for two bars out. MOT in November - I'll let you know if any problems!

Hi, I have the same issue on my (pre-lci) E93 2010. The 3 strips on the boot lid tail light aren’t working. But others are. To get this fixed would I need to get the whole unit or can I get a simple led bulb change?

Thanks

Guys, I know this is an old thread but maybe someone is still reading this. I have a problem where all 3 of my LED's are working but just arent as bright as the other side tail light. Any idea what can cause this ? I tried to connect the tail light using the other side connector plug and still the same, so i guess that rules out a bad ground or issue with the wiring, seems the problem is with the headlight itself. Any ideas ?

Its possible that one of the LED's its on its way out, and gives extra resistance, so the other LED's follow being darker.

Although an older post, this guide has just helped me to fit new LED's in my E93. Cut the back from the light away to reveal the board, use a 9v battery to identify the dead LED, de-solder then re-solder new.

Keep this thread alive, ooh-ooh, keep this thread ali-i-ive...

The taillight LED went out on me, and after reviewing this information I decided to just bite the bullet and buy a new unit for my 2007 E93. Which means I have an old right-hand side outer taillight unit available FOR FREE to anyone who wants to hack it open and/or maybe needs a second try at getting one right. Just pay shipping. I figure it will be about $20.
