Pulse width modulated L.E.D. automotive lights such as are currently being used on a few upscale luxury cars, need to have their minimum pulsewidth increased or standardized. They produce a distracting and often irritating strobing effect when viewed.

On General Motors cars that light the backup lights while parked and remote lock and unlock are activated. Pedestrians and drivers stop as if the vehicle may back up which should be a proper reaction. I have even taught my children this, people now have a tendency to ignore the backup lamps on vehicles in parking lots as well as creating inconvenient situations as cars and pedestrians stop for unoccupied vehicles. I have found myself driving past these vehicles when they are attempting to backup creating a close call. I know this seems trivial but I see potential problems and it seems to me a simple computer reflash could solve this disturbing trend. In the vehicle description I chose Cadillac Escalade though it seems to be most GM products.

Headlight installed height on taller vehicles such as category 1 and 2 trucks (commonly called SUV, crossover, van, pickup truck, etc.) is of such a design that it commonly (perhaps unavoidably) ends up blinding drivers in passenger cars at lower heights by directing the 'hot spot' of headlight low beams directly into the eyes of passenger car drivers. In addition, bumper height on these same vehicles is not designed to meet bumpers on other vehicles, resulting in higher than necessary injury and fatality rates. Please have someone contact me to discuss ways to develop safer vehicle designs and regulations.
