REVIEW OF OPTIONS CURRENTLY AVAILABLE, AND SUGGESTIONS FOR FUTURE RESEARCH DIRECTIONS FOR INCREASING MOTORCYCLE CONSPICUITY AND INCREASING PATH-OF-TRAVEL ILLUMINATION EFFECTIVENESS

Options available to the motorcycle owner, as well as original equipment and aftermarket products, are identified for improving forward illumination and conspicuity of motorcycles. Information was obtained from U.S. and foreign sources on such items as paint colors, auxiliary lighting equipment, reflective materials, and new motorcycle design for better conspicuity. On-the-market products (headlamps, auxiliary lights, taillights, turn indicators, reflectorized materials) were field tested to determine their relative effectiveness. Mandatory minimum standards suggested for street motorcycle lighting equipment are constant-on quartz-halogen main headlight (hi/low) with at least a 7-in. diameter lens; daytime modulated headlamp; constant-on combination turn signals and running lights with multiple direction lenses; four-way emergency flashers; frame or body panel mounted side running lights; side reflectors at fork, rear suspension, fenders; and reflectorized front and rear wheels (rims and/or spokes). Manufacturer and customer approved options for installation are dual main (hi/low) headlamps; auxiliary lamps (fog and driving); daylight lamps (yellow lens) front and rear; deceleration rate modulated stop lamps; mirror and/or handlebar end lights; and windshield perimeter edge fiber optics (glow edge). The most crucial area of research and development is automatic horizon/level compensation of main and auxiliary headlamps.
