What type of led is used in the nozzleheadmodule

I need a new led for the printingheadmodule , the one who indicates nozzle 1 or 2 and shows the heatingproces, i broke the left one and wanne change it with a new one, what is the type of led used? (there is no schematic of the U shaped board of the printing head)
My second question is: can i install a heated bed and the new rgb led add on kit on the same printer (controlled by the mainboard), or have i only place for one of the two?
The building of the kit was very fun and good quality, very good manual step by step, calibration was no problem at all, checked the voltage of the 5 stepmotor drivers (fine-tuning part) and everyone was correct from factory, an extra ballbearing for the z axis mod would be nice
tnx geert

Led type is not critical.
Heated bed and RGB module can be mounted simultanously.
