[Concept] TurboTorch Rear Zone Tail Light M8 suit NAMI

• [Concept] TurboTorch Rear Zone Tail Light M8 is an in-design potential future product featuring three high performance LED emitters for tail, brake and turn signalling that spreads the beam across the surface behind the eScooter.
• A Cobra Headlight style fixture with Dichroic Lens like that on Stonker would be ideal, however the design pathway will likely likely adopt three separate fixtures with wiring harness due to complexity with integrated approach.
• Emitters will be CREE XM-L2 emitters (or equivalent) at an efficient but not-too-cold 6000K colour temperature with 70CRI with wave lens diffusers producing 60x15 degree beam width to keep the beam on the surface. An external "top hat" (snoot) to further direct turn signals may be on the cards.
• Bracket design is in-scope ideally as a drop-in replacement for the factory stock NAMI Tail Light that resides on the NAMI Extended Plastic Fender for New Tail Light, ideally allowing for co-existance or replacement with the non-New Tail Light fender with fixture mounting via the extended fender brackets. Electrical interface via plug-and-play fitted M8 Green 5-pin male connector.
• Support voltage 12V.

• Weight: 250 grams (design target).

2. Dichroic Glass Filter explained:
   Colour shift is undertaken by a dichroic glass filter. Dichroic is a popular filter for stage and architectural effect lighting.When fixture light strikes the filter at an angle (such as spill), the path length is changed, and the colour of the light transmitted is different. The filter colour defines the colour in the throw / centre / spot area and the surrounding throw will be shift towards the opposite end of the colour spectrum (across the colour wheel)The green or blue centre is recommended for front-of-scoot clearance zone area as this colour is commonly associated with electric scooters under deck clearance area. Filtered Stonker is a perfect auxiliary light to accompany the traditional white headlight as it extends your blue under-deck light area to where the white headlight spot lands, creating a visual indicator of where your are traversing. For rear-of-scoot clearance zone area, red is suggested. The red will appear as an orange/amber/yellow when viewed from the side.Check out the eScootNow video to get an idea of the colour shift in action. For defining clearance area zones, a 35 degree tilt downwards of the fixture is recommended as the direct light will differ in colour to that reflected off the ground. Dichroic glass reflects certain spectrum (colours) back into the fixture reflector, which trades efficiency loss with visual effect and places more stress (heat) on the emitter/fixture.An excellent article on Permacolour Dichroics and How they work is published here including the below diagram:
