Fish tanks signals

[heath94]

Has anyone done a fish tank mod that allows the light to work like the Turn park light. The standard mod it flashes opposite of the sig. light, with the side marker. I'd like it to work with tie other front light. Is there room for the larger bulb? Ideas?

There is a large bayonet base bulb that is bright. 912 and is usually used in the trunk.

I don't know of a small base dual element bulb though.
