WHAT'S NEW
新警告灯
Sireno Signal Mfg. Corp. is marketing a new warning light, the Gyro-Ray. The unit gives three dimensional protection for emergency vehicles. Two red sealedbeam bulbs revolve 360° horizontally. In addition, one white sealed-beam bulb gyrates through a 90° arc, while at the same time revolving 360° horizontally with the red bulbs. The two red bulbs can be operated independently from the white beam, if desired, through a two-position switch, provided as standard equipment. Blue or amber scaled-beam bulbs can be supplied in place of red, upon request.
