Federal Signal Model 19

In my Model 19 it´s a 4503, 40 Watt Sealed Beam Fog Par 36
But i think you can use the 4415 too
Indeed. For a shelf display either are fine. The 4503 sports a 40x5 degree spread pattern that should produce a good snap or flash when viewed off axis, whereas the 4415 is 50x25 degree generates a more pulsating flash. The 4414 is what John Dorgan put in my 78 when he restored it.

Regardless, your work is awesome and displayed beautifully!

The 4503 and 4415 has the same spread, 40x5 degree.

It is only the Voltage and Wattage that differs.
Rated 14V, 40W for the 4503 and 12,8V, 35W for the 4415.
That means that you have slightly more power in 12V for the 4503 but that sealed beam is now obsolete.

The 4414 has the 50x25 degree spread and will not have the right flash.
