The way I did it was to just add separate LED's. As a component. Printed some brackets with holes in it so I could insert these LED's in it and clamp it to whatever part of my printer I wanted them to be.
I would not waste my time with putting in such a light bulb, chances are they eat a lot more power from your printer than just a few small LED's.
