use polycarbonate lens in terms of waterproofing

make enclosure taller or squintier

headlights very big, taillight shape narrower, sidelights very tiny, high mounted brake light longer

high mounted brake light a lot of space to work with

tail lights will cover brake lights and signal

amber colour for signal lights, brake lights are red

similar taillights and high mounted brake light long rectangles

stick on side mirrors - tiny round lights (last year)

• less power for small lights (side mark indicator lights)

10cm board with 4 leds equally spaced

the entire light doesn't light up - it's a beacon of light little (pin lights)

• giant lens with little bright light in the middle

max thickness is 3-4mm thick for material

headlights are already polycarbonate casing

make diffusion materials different colours and lens cover is clear

headlights thermoformed

can maybe make the headlights not a bulb shape but a nicer looking futuristic design ?

casted plastics being a good option

3d printing but issues with clear

• cant thermoform over .5cm thick

spread heat onto larger surface with pcb and attach the heat sink

natural airflow to cool down high mounted break lights??

generous airflow for headlights

for the heat sinking assume lights always on to not risk firmware bug

estimate cooling needed - based on power expected to consume and translate into heat. figure out the mass of material needed to transfer into for certain rise in temp of material - specific heat capacity of material
or data sheet of heat sinks

size of heat sink (maybe 60x30mm finned)

viewing angles for the leds

• side lights are the most important

• wide-angle lens will disperse the lights more and make them dimmer

maybe 4mm thick acrylic for diffusion ???

how far do leds need to be spaced ???

can you see the light from 30m away ??? (testing this week)

• estimate luminosity at 30m away

what is the minimum number of leds for 30m away and size of the enclosure ???

flat shape for the plastic covering instead of rounded ????

pretty complicated looking design

casted plastics but max temp is low ?

• (***polycarbonate resin has a working temp range from -20-140C)

3d print the part and cast the mold

resin casting - max temp the plastic can withstand is an issue

if lights too bright than we can start diffusing until reference light intensity is met

• diffusion material determined after testing

right now determine enclosure spacing

control one led strip per light enclosure (multiple maybe ???)

can focus on aesthetic hehe

test leds and adrian will look into what will look the nicest
