Now we deal with the case lighting. The cold cathode is incased in a plastic case to protect it and defuse the light. We will need to remove the casing very carefully. Most cold cathode tubes have mercury vapor in them this is very dangerous if it was broken. Avoided damaging the bulb at all costs as mercury vapor has been linked to brain damage and cancer. so be careful.... unless your some arch-villain with a diabolical plan.

Using a dremel tool and a cutting disk on the highest speed use the wheel to melt the plastic all the way around near the caped end with the leads coming out of it. Taking care not to cut to deep and possibly damaging the tube. Once separated use a blow dryer to heat up the glue in the cap with leads. When the glue gets hot it will become soft and allow you to pull the wired and bulb free. Some coaxing may be needed and maybe a bent paperclip to remove some glue before it will be freed. I strongly recommend doing this outside in the open air do if you mistakenly cut to deep or otherwise break the tube you can be relatively safe with good ventilation. Once removed the bulb is very fragile so take care with it not to hurt it. or it may hurt you in return.
