My Ride: 2005 545i Sport
I have more pictures at home. I will post one (i forgot yesterday).
It's 10 LED in each lamp, not 5. I got 4 set from the link.
These are not plug & play. I'm an electronics engineer, so it wasn't difficult to build something with them.
Why did I bother to post the link if you see something else?
The manufacturer says Min: 90,000mcd Max: 130,000 mcd, DC Forward Current: 100mA, Viewing Angle: 60 degree.
I do not understand why you only remember the minimum.
They are NOT running at minimum power. In my lamp they get 130mA (it's safe until ~150mA for a short time).
You can imagine i get more than 100000 mcd out of them.
So... 100 cd at a viewing angle of 60 degree how much lumen puts out??
It seems to me it's more than 85lm each LED.
85 X 10 = 850 lumen vs Putco's 240 lumens using 3x Nichia LED modules.
You buy those Putco's if you like them. For me, my lamp is way much better.

10 LED's within the surface of the reverse lens is impressive.
I'm just not sure that anybody outside of an electrical engineer could pull it off. I was simply offering a more mainstream resolution to wanting more white light. I think 240 lumens x 2 = 480 lumens is more than enough light to reach 25 or so feet from the rear of the car.

If you're interested, we discuss the details in private.
