Automotive lighting
• Forward illumination– Headlamps
• Low beam, High beam– Assistant lamps
• Driving lamps, Rally and off-road lamps, Fog lamps, Cornering lamps, Spot lighting
• Signaling devices– Stop lamps (Break lamps)– Centre High Mount Stop lamp– Turn signal – Reversing lamps

LED lamps at Automobile
• Centre High Mount Stop Lamps (CHMSL)– First application of LED at Automobile
• Stop lamps (Break lamps)– Fast lighting then incandescent bulbs
• Turn signal• Head lamps recently

How can we use LED lamps for VLC at automobile ?
• Vehicle-to-vehicle communication– Information exchange– Auto driving by following the car ahead
• LED traffic light to vehicle communication– Idle stop– Car black box
• LED signboard to vehicle communication– Vehicle condition indication– Service information– Advertisement

Vehicle-to-vehicle VLC with an unknown driver
• Information exchange using the voice communication– Exterior device condition which driver is unaware – Ask a way
• Speed information– Reduction of speed by sudden stop of car ahead– Traffic information map

LED traffic light to vehicle communication using VLC
• Idle stop– Receive the red light interval from LED
traffic light and save gas
• Car black box– Save the traffic signal information.– Check the stored data after car accident.

Signboard communication at the Gas station
• Service information– Oiling amount, price– Fuel efficiency– Possible mileage according to oiling
amount and fuel efficiency
• Vehicle Condition– Maintenance information

Signboard communication on the road
• Interworking with Navigation system– Traffic information– change a route
• Advertisement on public transportation– display on the monitor in the bus or taxi.

Considerations
• Is there any kind of barrier?
• What application can be realized only by VLC?
• What can be the VLC Killer application?
