Hi all
the following is chunks taken from the Victorian Road Safety (vehicles) regulations 1999. This covers the stuff not covered by Australian Design Rules.
Design Rules
The design rules allow six (6) lights on high beam and two (2) on low. All Lights to be symmetrically mounted around the centreline of the vehicle with minimum distance apart as well as minimum and maximum heights for low beams, but as we don't generally change the low beams its probably irrelevant.
The extra (driving) lights therefore must be symmetrically mounted and in pairs.
Maximum height for
driving lights is not a problem but mounting them on the bull bar top is normally an issue due to the restriction in forward vision (defined under other rules) not because the light is too high.
Light outputs must be approxiamately equal: thats the wattage or lux or glowing ember measurement not the beam shape so there is no restriction on mixing spots and spreads.
Personally think spots are a waste of time if your spreads are set up properly with decent headlights but I have already had my two bobs worth on that in previous posts.
this is from the regs, I cut out the motorcycle bits
PART 8¡XLIGHTS AND REFLECTORS
Division 1¡XGeneral requirements for lights
75. Prevention of glare
A light, except a high-beam headlight, fitted to a vehicle must be built and adjusted to provide the necessary amount of light, without dazzling the driver of another vehicle approaching, or being approached by, the vehicle.
76. Pairs of lights
(1) If lights are required under the Vehicle Standards to be fitted to a vehicle in pairs¡X
(a) a light must be fitted on each side of the longitudinal axis of the vehicle; and
(b) the centre of each light in a pair must be the same distance from the longitudinal axis of the vehicle; and
(c) the centre of each light in a pair must be at the same height above ground level; and
(d) each light in a pair must project approximately the same amount of light of the same colour.
Sch. 8
Division 2¡XHeadlights
77. Headlights to be fitted to vehicles
(1) A motor vehicle must be fitted with¡X
(b) a pair of low-beam headlights if it has 4 or more wheels
(2) If a motor vehicle built after 1934 can travel at over 60 kilometres an hour¡X
(a) each low-beam headlight mentioned in sub-clause (1) must be able to work in the high-beam position; or
(b) the vehicle must be fitted with¡X
(ii) a pair of headlights that can work in the high-beam position.
(5) Additional pairs of headlights may be fitted to a motor vehicle with 4 or more wheels that was built after 1969.
78. How headlights are to be fitted
(1) The centres of low-beam headlights fitted as a pair on a motor vehicle with 4 or more wheels must be at least 600 millimetres apart.
(2) However, sub-clause (1) does not apply to a motor vehicle built before 1970 if the centres of its low-beam headlights¡X
(a) were under 600 millimetres apart when the vehicle was built; and
Sch. 8
(b) are not nearer than they were when the vehicle was built.
.
(4) The centre of a low-beam headlight fitted to a motor vehicle built after June 1953 must be¡X
(a) at least 500 millimetres above ground level; and
(b) not over 1„ª4 metres above ground level.
80. How additional headlights are to be fitted
If 2 or more additional headlights are fitted to a motor vehicle with 4 or more wheels, the additional headlights must as far as possible be fitted in pairs.
81. Performance of headlights
(1) When on, a headlight, or additional headlight, fitted to a vehicle must¡X
(a) show only white light; and
(b) project its main beam of light ahead of the vehicle.
(2) Headlights must be fitted to a vehicle so their light does not reflect off the vehicle into the driver's eyes.
83. Changing headlights from high-beam to low-beam position
(3) When a headlight fitted to a vehicle is switched to the low beam position, any other headlight on the vehicle must operate only in the low-beam position or be off.
Hope this helps.
