change colour of led
I have a small problem...the default color of a boolean led is green and i want to change it's color to red if some condition is true. I used property node (the property being colors[4]) for the LED and wired a color box constant with value red to it.But it shows a broken wire and tells me that types are incompatible.How do I fix this error?
Thanks,

Well, why don't you just color the TRUE state red using the coloring tool, then just wire your boolean condition to it? 🙂
That's probably the way to go!!! 😄
(If you still want to use a property node, just open the context help while hovering over the property. It will tell you that it wants an array where each array element is a cluster of two colors. Check the help for details).
If you need an LED with more than two colors (e.g. off, red, green), use a colorbox made to look like an LED. Here are some old examples:

Thanks altenbach,
I saw ur example...but is there no way an led can be made to exhibit 3 states using a property node?I don't want to create a colorbox as a led because it doesn't go with my code
i just want to change color of led to red when my boolean condition becomes true.

i just want to change color of led to red when my boolean condition becomes true.Then read my paragraph in parenthesis above! Wire an array of color pair clusters!
The colorbox is however a much cleaner and more efficient solution, you could do something like the following:
(this has two colors for ON, while off is the same Mix&match according to your requirements)

You can always create the correct datatype by just right-clicking on the property and selecting "create constant". you'll get and empty array of the right type, except that the colors are numerics instead of color boxes (no big difference ;)). Now just right-click on each numeric and select "replace.." and pick a color box constant.
Now select the desired color.
See how far you get. 🙂
Or you could do the following:
Resize the built array to two or four elements as needed. Check the help (right-click on the property node and select "help for colors[4]"). It's all there!

Hi Veeru,
the LED only takes 4 colors (with a purpose for each). But you can change those colors anytime, so it's up to you how many colors you want to show.
BUT:
The more colors you want to show, the easier it will be to use a color box instead!!!
