嗯,我也查了一下WA的规定,如下:
1 DAYTIME RUNNING LAMP
Daytime running lamp means a lamp facing in a forward direction used to
make the vehicle more easily visible when driving during daytime.
The retro fitting of daytime running lamps is acceptable provided the lamps
comply with Australian Design Rule (ADR) ADR 76 and are fitted as per
ADR 13:
Colour White
Number Two
Position: Fitted symmetrically (same position on both sides of the vehicle)
at the front of the vehicle.
In height: above the ground not less than 250mm or more than
1,500mm.
Not more than 400mm from the sides (extreme outer edge) of
the vehicle; at least 600mm apart between the inner edges, may
be reduced to 400mm where the overall width of the vehicle is
less than 1,300mm.
The angle of the beam may only be outwards 20° and inwards
20° and upwards 10° and downwards 10°.
The daytime running lamps shall be switched ON automatically when the
device which starts and/or stops the engine is in a position which makes it
possible for the engine to operate.
The daytime running lamp shall switch OFF automatically when the front fog
lamps or headlamps are switched ON, except when the latter are used to give
intermittent luminous warnings at short intervals.
Furthermore, all other forward facing lamps (as listed above) must not switch
on when the daytime running lamps are switched ON.
