Preferred replacement light bulb for TNG phaser?

I'm going to let a friend borrow my TNG phaser toy for her Halloween costume this year, but I need to replace the lightbulb. I'm assuming it's a 3v incandescent bulb, but I'm also wondering if there is a preferred replacement in the ST community, something like an LED? Those little bulbs appear to come only in multiples and because of that cost a lot to get one bulb. So if I'm going to spend that much, I'd rather upgrade if possible.

 

I wonder if they make LEDs to fit that. Maybe ACE hardware?

 

There used to be a hobby store in my town that sold model kits, train sets, high-end remote control airplanes, etc. You could get individual LEDs there too, instead of having to get a bundle of them.
