Drew, fuses can only be blown if you install resistors of *lower* resistance than those "load equalizers", as that would increase the current - not the other way around.

If one of the LED's burn out, does it trigger the "lamp out" warning on the info display?

LEDs never burn out under normal conditions, unlike incandescent bulbs. You can burn them, of course, by applying very high voltage - but this is a purely hypothetical situation in a car.

You are dealing with a double-edged sword here. LEDs draw very little current. Now, this replacement will have numerous LEDs and then you have your load resistor. This resistor will use up most of the current in this scenario.
It will all depend on how close to the edge you are within the tolerance band. On the low side and you could. On the high side you won't because you are moving towards the low side.
Since there are multiple LEDs in the assembly I doubt you would need to be worried and be checking it all the time. LEDs come in different sizes. Therefore you could have an assembly with a whole lot of little ones or you could have one with just a few.
Find out how many LEDs will be in each assembly and evaluate it from there.
Just my $0.02.

I want to know if I should check the rear lights periodically or if I can trust the display.

Oh BTW, vadim, since the coupe uses a vertical bulb for the brake lamp, I was thinking that formymercedes.com's Red snake light LEDs may do the trick instead. I bought a couple of these for another purpose and they are similarly bright as the LED bulb's LEDs. Since they're simply LEDs with pre-wired resistors and a two foot long lead, one could somehow wire them into the bulb socket (and load equaliser) and position them into the lamp assembly. This will save you the need to customise a lighting rod.

Hey, how's everyone do'n? It's so cool to see how so many of
you all are into LEDs. It looks to me like there are a lot of
people knowledgeable about LEDs.:p :p I could use some
new ideas for use of LEDs.

hey Skids,
I tried to use the search function to search for the instructions for the modification of the lights in the exterior rear view mirror, could you please tell me where you posted the instructions or maybe post it here?
thanks a lot!!

It looks like a LED/light manufacturer needs to design an LED replacement "bulb" that has an outside row of LED's that face towards the reflector, to avoid hot-spotting. Seems fairly simple to do

I think the point of this design is to spread the light better rather than for heat dissipation.
The picture is of a brake/tail.. they also have just brake

Surely if you can afford a Mercedes-Benz, you can afford the price of the load equalisers!

Is it just me or do these mass produced resistors ( http://www.liean-gimn.com/products/l/11.htm ) look amazingly like the load equalizers that "are specificially designed by the manufacturer of the LED bulbs to complement the bulbs and to dissipate the heat effectively" ?
