Modes of the speedlight

The final section of Moving Modes is RIDING THE TURN INDICATOR. Refer to RIDING THE TURN INDICATOR FIGURES (30mph) on page 19. The Speedlight System helps us to know when a vehicle “riding the turn indicator” is likely to turn. Vehicles may pass several driveways or go several blocks with the turn indicator on before making a turn. Often it is left on indefinitely by mistake. The following traffic has to pay attention to gauge how fast the lead vehicle is going.

Are they going at a constant speed? Are they accelerating? Are they decelerating or going slow enough to negotiate a turn? The following traffic’s attention is distracted from all other aspects of driving as they monitor the vehicle in front of them. With the Speedlight we can easily view the speed of the lead vehicle and “see” when they accelerate and “see” when they decelerate. We can also “see” when they are going slow enough to negotiate a turn without giving them our undivided attention. We can anticipate their intention to turn by seeing when they are going slow enough or decelerating fast enough to do so.

CONSTANT SPEED/ RT. TURN INDICATOR ON
The Speedlight strip is on low. Lights illuminated in from ends with static display indicating speed of vehicle.

  • Panic Light on low.
  • Taillights: Left one off. Right one on high and flashing.

ACCELERATION WITH RT. TURN INDICATOR ON
The Speedlight strip is on low. Lights turning off sequentially out from the center relative to rate of acceleration.

  • Panic Light on low.
  • Taillights: Left one off. Right one on high and flashing.

DECELERATION WITH RT. TURN INDICATOR ON
The Speedlight strip is on high (braking). Lights illuminating sequentially in from the ends relative to the braking rate of deceleration.

  • Panic Light on low.
  • Taillights: Left one off. Right one on high and flashing.
