4 Classification Naming
4.1 Classification
The warning lamps may be divided into warning lamps for police cars, fire engines,
ambulances and engineering rescue vehicles respectively according to their different
purposes.
4.2 Naming
The product model of warning lamps shall be named according to the following
structure and requirements:
5.3 Optical warning devices
5.3.1 Type of optical warning devices
The gas discharge lamp, light emitting diodes (LED) and filament lamps stated in GB
15766.1 may be adopted as optical warning devices of the warning lamps.
5.3.2 Luminous mode
The luminous modes of the primary optical warning device of warning lamps include
rotation, frequency-flash, pulse, frequency-change and multi-lamp circulation.
5.4 Letters and symbols
There shall be clear and standardized letters or symbols on or nearby switch and
press key to indicate their functions and on-off condition; the letters shall be in
Chinese; if necessary, other language may also be used. Where fuse is used, the
rated current of fuse shall be clearly indicated.
The above-mentioned letters and symbols shall be clear and durable.
5.5 Electrical property
5.5.1 Power supply
Rated voltage of power supply for warning lamps: DC12V or DC24V.
The warning lamps at rated voltage shall be able to withstand polar inverse-wiring test
for 1min. Except fuse, there shall be no other electrical fault.
If the opening and closing of warning lamps are controlled by soft switch; the standby
current of warning lamps shall be less than 5 mA.
5.5.2 Conductor
The conductors used for warning lamps shall be in accordance with the requirements
of GB/T 19666.
5.5.3 Wiring
The conductors inside warning lamps shall be provided with proper protection so as to
ensure these conductors don't contact the components which may cause any damage
on conductor insulation. Where the conductors need pass through metal holes, the
metal holes shall be chamfered and shall be free from any sharp edge; non-metal
The noise of warning lamps shall be less than 55 dB(A) when operating at full load
under rated voltage.

DC9.0V voltage, the luminous intensity on the reference axis of each primary optical
warning device for warning lamps shall not be less than 90% of those specified in
Section 5.7.
For warning lamps with DC24 V rated voltage, the warning lamps shall be able to
operate normally where powered by DC18 V~DC32 V voltage, and the luminous
frequency shall be within the range specified in Article 5.8.1; where powered by DC18
