For 1:25 scale models.
This second light kit is fitted using the same methods as detailed for the Ecto-1A. The difference is that each of the two roof bar lights house four flashing blue leds (two on either side of the units - the central section on each is blanked off).
Drill through as per the 1A kit, installing two flashing blue leds on each side of the two light bar units.
Also there is a flashing red led for the roof beacon with this set, as unlike the 1A there is no red plastic housing supplied with the traditional Ecto-1 kits.
The headlamp and tail light set-up is the same as the 1A.
