Flashing Roof Lights

Is it possible to create flashing roof lights for a locomotive similar to the F40PH? On the F40, when one uses the bell, a pair of lights on the roof also flash, like ditch lights. Is there any way to be able to do the same for the AEM-7 locomotive so that it also has working "roof lights?" They exist on the locomotive, but do nothing.
I have attached a photo to show what I mean.
