I'm planning to change the repeater lights on my dashboard to LED - in the strong sunlight here in Australia, they are very hard to see and it's this I want to address.
I suspect the actual changeover is easy enough however I've done this on another bike and that's when I learnt that LEDs only work if they're put in the right way around.
With most of the idiot lights, this will be easy to spot, they'll either be working or not. But how do you check if the fuel warning light is working? The side of the road is not the best place to discover you put the LED in wrong.

My I assume that the fuel warning light will come on if I disconnect the low fuel light under the tank?

You’re putting too much thought into this! 
Just change it over when the OEM bulb is already indicating low fuel.

All my led lights are bi polar, they work either way round.

I didn't know you could get them. I'll have to ask when buying.

This bike is really making me feel inadequate.
How the hell do you get those idiot lights out? I'm not even too sure I can work out where they are and aren't too happy about pulling on wires.
At least the headlight is easy to get off and put back on.

Are all the globes white or do I have to source some coloured LEDs?

In rubber bushings.  Most, if not all of the tiny bulbs on my 2012 C5 were T10 type.  I think they switched some bulbs to a smaller type at some later year.  You might have to pull yours out to see what you got.  I used a big and LONG pair of needle nose pliers to get at mine, my hands are too big to be useful for this process.

Thanks axeman.

​I changed the dashboard lights on the 500 today. Well, not the backlight for the speedo, you only need that at night and you don't need a spotlight there. The others though, are so dim you can only see them at midnight down a deep cave. In daylight? Fuggedaboudit.
So I fitted LEDs, 3xT10s and 3xT5s.
I could only get bi-polar in T10 from Jaycar so I went for normal LEDs (cheaper)
I did have to go back and get a bi-polar LED to go in the turning indicator repeater because with the normal one, it'd flash on one side but not the other, change it around and the other side would flash. Fit a bi-polar and it worked a treat. Didn't affect the flash rate either.
The hardest part of the job was getting the damned things out, the holders are rubberised and just didn't want to come out.
The low fuel light was done when the light had just come on - glowing when on the side stand and off when upright. Made it very easy to test.
Anyway, I got it all sorted, now I can terrify high flying jet pilots in full daylight.

And a photo. Typically, I'd moved the bike to a spot where the fuel light didn't come on and it was closer to dusk so everything is darker so the lights glare, something that's magnified by my mobile phone. But here it is.
