The Problem› Color Blind have a hard
time distinguishing red and yellow
› Especially bad at night

History› Lester Wire designed the
traffic light in 1912› At first there was no yellow
light› Other than adding yellow the
design has been untouched

Attempts of change› Evgeny Arinin redesigned
the light with different shapes› Self driving machines
› Taro Ochiai redesigned red light with cyan X inside

My idea
› Add a sticker to change the shape of the light› Cheap and easy› Nothing has to be replaced

Things to consider
› LED lights are being pushed› Last up to 11.5 years
› High temp vinyl can survive up to 225 degrees› Also waterproof

Application Process
› A sticker will be created for each light› attaches to pole arm
› Polearm can extend to apply
› Light hood can be used to guide pole

The Math
› Sticker and pole arm part are either 8 or 12 in in diameter
› Yellow light is 16ft above ground› Pole arm should extend up to 22.5ft › Person can stand 16ft from light and
apply at 45 degree angle
