Hi All,
I have just been reading through the Code of Practice with regards to vehicle modifications on the Queensland Transport Website.
Below is a copy of one of the pages on headlights. According to this it seems that it is now legal to fit lights above the old height limit of 1.4 metres which means mounting on the roof is OK.
Here is the page:
"Headlights
Some new factory fitted headlights may appear to have a blue or yellow tinge. Advice from
the federal Department of Transport and Regional
Services (formerly the Federal Office of
Road Safety) is that these colours can sometimes be seen on some of the new technology
lights when viewed from the side. However, these lights do emit white light in the required
angles and comply with the ADR’s.
Note that a main (high) beam headlight under the ADR’s, and now under TO(RUM-VSS),
may be fitted at any height above the ground compared to the previous height of 0.6 m to 1.4
m in the Traffic Regulation 1962.
Motorcycles, including motor tricycles, with twin headlights side by side may have one light as
low beam and the other as high beam. That is, the high and low beam do not need to be
symmetrical about the longitudinal centre line of the motor cycle, including motor tricycle(s).
Blue Headlights
"Blue" halogen bulbs are a recent innovation in vehicle lighting technology. They operate at
higher temperatures and provide superior illumination to the conventional halogen bulb.
Historically, the white light emitted from headlamps on motor vehicles has been generated
from incandescent light sources and contains a predominance of red/yellow frequencies.
This has become the accepted norm for white light. The new bulbs, which are actually
"whiter" than the existing bulbs, contain less of the red/yellow frequencies and more of the
blue end of the spectrum. The bulbs may be perceived as a very light blue.
The envelope around the filament of these bulbs is dyed blue, primarily to reduce the
red/yellow frequencies that are always present in light produced by incandescent filament
bulbs.
Motor vehicles have been required to comply with Australian Design Rules (ADR's) for
lighting since October 1991. ADR 13 mandates the number and position of lamp assemblies,
ADR 46 prescribes the photometric requirements of the lamp itself and ADR 51 is the
standard for filament bulbs.
ADR 51 accepts ECE regulation 37 as an alternative standard for filament bulbs and
prescribes the dimensional and photometric requirements for filament bulbs (including
headlamps). This ensures inter-changeability and correct functioning when installed in a
complying lamp unit.
All complying bulbs sold in Australia would be marked with the "E" mark and possibly the
words "Suitable for European Use". The packaging may also indicate compliance with ADR"
Just thought some of you may be interested in this.
Cheers,
Brett
