Jenna, do you want me to send you the light wavelength analysis we had done on the globes? I had to supply it for a similar "offence" in QLD as part of a defence.
Basically the wavelengths emitted by our lights are 100% WHITE on average, and the same as natural daylight...BUT when next to an obviously yellow light it appears 'blue' as white LEDs are less yellow.
So basically they don't emit blue light at all, but they are LESS yellow than a normal light. It's a massive difference when it comes down to the letter of the law. So much so that they actually fall within the allowable deviation of colour allowed on a standard bulb.
The same thing can be said for putting a white LED next to a blue one, you'd never say the white LED was blue in comparison
Always good to know the specifics
A nice bit of info from QLD transport-
"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.
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.
