Lighting and Horns: Description and Operation

96 - Interior Lights

The interior lighting in the Boxster/S (987) is based closely on the concept used in the previous model. New are the white LEDs for instruments and controls, which offer better illuminating power than the yellow LEDs used in the previous model. This has improved the readability of the instruments, particularly at dawn and dusk. The white color of the new LEDs is also substantially more comfortable for the human eye due to its composition. Another advantage is that it makes yellow and red warning symbols and lights stand out more. Lastly it gives the interior a higher quality appearance and creates a more pleasant ambiance. Two footwell lights have additionally been incorporated for improved illumination of the interior.

Interior Light

The interior lights and footwell lights are supplied with negative potential. This takes the form of a PWM (pulse width modulated) signal which is altered accordingly with a programmed dimming time.

Orientation Lighting

The LEDs in the interior light and in the footwell lights are supplied with positive potential. This also takes the form of a PWM (pulse width-modulated) signal which is altered accordingly with a programmed dimming time.







Safety and Exit Lighting

The addition of automatic coming home lighting to the exit lighting represents yet another major increase in convenience. Automatic coming home lighting is preselected via the light switch. When the door is opened or the vehicle is unlocked using remote control, the front fog lights, tail lights and license plate lights come on for 30 seconds to illuminate the surroundings. In vehicles with the Sport Chrono Package Plus, the duration for which the lights stay on can be changed in the �Individual Setting/Light" menu option.

The sun position sensor in the automatic climate control system monitors the ambient brightness to prevent the lights being switched on unnecessarily.

Bulbs rated at 12 V, 10 W are used for the safety and exit lighting. These bulbs are activated by the respective door control units.

Power Saving Cut-off

The interior lights are supplied centrally with positive potential via terminal 30G. In order to prevent interior lights which are left on permanently form draining the battery, terminal 30G is switched off when the CAN signal "load switch-off" is active. This CAN signal is generated centrally in the driver authorization controller (PAS - Porsche Access System).
