Direction indicator, brake light, parking light.
Type
Combined light for direction indicator, brake light and parking light.
Clear light for direction indicator. The direction indicator bulb is amber-coloured and of type BAU 15s 21W.
The bottom of the light cluster is used for the brake and parking lights. The outer section is a combined brake and parking light. When the parking light
is lit, PWM voltage at 22 % is supplied to the lamp, reducing the light strength. When the brake pedal is depressed, the PWM voltage goes up to 100 %
and the lamp shines at full strength. The adjacent lamp is normally used as a parking light only. But, if the ordinary brake light lamp were to fail, it works
as a substitute brake light. The bulbs are type BA 15s 21 W.
