kossel delta plus lighting mod

this is a mod that fits my corners to give low level lighting great for doing time laps or just to light up when printing.
watch the video.
either use the battery box to power lights or you can hard wire to main board. I used pin 11 as in pic with main board and setting code as below in Configuration_adv.h

// Define a pin to turn case light on/off
//#define CASE_LIGHT_PIN 11 // Uncomment
//#if PIN_EXISTS(CASE_LIGHT) // Uncomment
//#define INVERT_CASE_LIGHT false //uncomment Set to true if HIGH is the OFF state (active low)
//#define CASE_LIGHT_DEFAULT_ON // Uncomment to set default state to on
//#define MENU_ITEM_CASE_LIGHT // Uncomment to have a Case Light On / Off entry in main menu
//#endif // Uncomment
