Why These Matter
The GE 4416 is the original‑spec high‑output sealed beam used in many 1960s–1990s emergency light bars. These are getting harder to find, and collectors prefer genuine GE units for brightness, beam pattern, and authenticity.
Shipping
Bulbs are packed with extreme care to prevent filament damage during transit.
