Green is the easiest to see.</p>

I eventually ended up de-soldering the LEDs, but they work fine in the module. These are definately very bright, even at 5V, but they are only very bright looking straight at them from the front, whereas from the sides they are less bright. Just as a note, the wall mounting clips have double sided adhesive on the back of them, although you cannot see this from the picture. Mine came with white leads, and unlike the description, the leads and the sockets are not polarised such that the modules cannot be wired in reverse. Linking these things together in chains does not decrease the brightness at all,so there is no need to link them all individually to a power source.</p>
