After a bit of research today I found out that its unlikely to be something wrong with the control box. below are my findings:
The LED bulb I got from the C5 alive shop ended up having dry solder joints and the resistors snapped off, due to this it must of buggered up one of the LEDs and therefore made it unusable
The LED bulb I made at work had a simple problem, cracked solder joints due to fragile soldering and leads.
I then found a unused Red LED (these are high quality high tolerance LEDs that come in their own metal casing and can stand allot of abuse(my company use these for gas leak detectors and are designed to be used in harsh environments and can stand a wide range of volts and current)) and I have now fitted it in my c5. hopefully this will last a long time and If I receive any more issues I will update this topic accordingly
fingers crossed
