Yeah it would been thinking maybe i could take apart an laser pointer or something but I don't know much about electronics or electrical work.
Adding a laser to the helmet would be relatively easy. A surplus store should have everything you need for less than $2.
There are these amazing stores near me called AX-MAN Surplus where I get all my misc parts. I bought a bunch of 2 light, 2 battery LED keychains for 50¢. Use them for adding lights to figures (like the 6" Bandai C3PO). They used to have thousands of polybagged Kenner Boba Fett figures for 75¢ each.
