Adding arrow heads on traffic arrow

[Da-Sarge]

Does anyone know how hard it would be to add the arrows to a normal traffic advisor? I've got an 8 head traffic adviser but looking to add the additional heads for traffic arrow

Maybe.
What make and model traffic advisor? And also what model traffic advisor controller?

If you are talking about adding more lights, I would first make sure the controllers output can handle the extra wattage, and the reduction in impedance.
