barrel light

[painkiller]

hi guys the bb unit in my sturmtiger has stopped working,as it is slightly different to heng long i can`t seem to get a replacement,this tank was made by matarro but now has all heng long electronics including the rx18 board,does anyone know of a way to wire up a light that could be placed in the barrel so that when the recoil or kickback button is pressed the light would flash giving the impression that it is firing,any help would be great,thanks
