John Wayne Airport (SNA) in the US has installed AirEL’s illuminated identification numbers for on-field operations vehicles to increase their visibility and improve safety for crews working on its dark runway.

The new vehicle markings, which use electroluminescent technology to light up, can be easily seen from a distance of 700ft to 1,000ft.

John Wayne Airport airside operations manager Jeff Rountree said: “We did not do this in response to a close call. We did this as an enhancement.”

The illuminated signage was originally developed by AirEL for police operations to easily identify squad cars at night.

AirEL sales senior vice-president Garwood said: “It is one more layer of safety. We are all responsible to know where vehicles are on the airfield.”

Officials at Long Beach (LGB) decided to install the illuminated numbers on the rooftops of airport security vehicles. The airport security division, part of the Long Beach city police force, uses the illuminated numbers on cars used by supervisors and gang units.

Besides John Wayne Airport, Dallas-Fort Worth International Airport (DFW) is using the illuminated signage on top of airport police vehicles and the sides of airport operation trucks.

Additionally, Reno-Tahoe International Airport (RNO) and Minneapolis-St Paul International Airport (MSP) are using the illuminated signs on snow removal equipment.

John Wayne Airport is owned and operated by the County of Orange. The five-member Orange County Board of Supervisors appoints the five-member Orange County Airport Commission that recommends to the board for development, maintenance and operation of the airport.
