From the pic it looks like a fluorescent bulb with a contact ring at one end. Just solder two wires and a battery to one end, stick in in a muzzle loader and fire it!
Don't actually try soldering anything to a battery by the way, but if you did use a battery holder you may as well just fire the light module too.
Real tracer rounds add a touch of white phosphorus to burn off when set off by the charge in the chamber.
Since this is KNEX, you might have to adapt a LED throwie to tack on to the end of these translucent rods. Hearing aid batteries are super small coin cells but I don't know how much power you can get out of them for an LED. Of course, this changes the characteristics of your projectile round and will have to improve your launching mechanism. Maybe you should paint your rods with glow-in-the-dark paint, charge them up with a light source and let it rip. Otherwise, if they are hollow, try to fill them up with the chemicals from a glow-stick or those novelty necklaces. They only last a short time so you will need to change or refill them after a few hours. Good luck.
Genious... or just use glow sticks themselves. You'd need to wait them and make sure they're stiff and sized right but otherwise they should fit nicely in knex barrels.

You could try to put phosphorescent paint on them.

One rather larger problem- the 'LIGHT MODULE'

Although, caitlinsdad does have some very good ideas, the glow in the dark paint sounds the quickest and easiest - or glow in the dark tape.
