Hi Nobrot,
PM answered, I would say be careful with EL sheets, some manufactuers give them a life of 100 hrs at full illumination. You can get better ones but as is always the case you get what you pay for.
I agree with agrasyuk, use LED's if possible the clear panel can be customized for you to accomodate any type of installation, the spacer is cut out only were illumination is required.
Hope this helps
