The operating frequencies of pwm (pulse width modulation) led's (light emitting diode) is to low for some viewers! this is a very real condition known as flicker fusion or critical fusion frequency and does not have the same effect on all viewers. a recall is needed to fix this travesty that has gotten out of control. it started with cadillac's srx around 2000, now in 2010 ford and volkswagen have gone overboard and just about all the vehicles they build are operating at this dangerous and deadly frequency. the operating frequency needs to be >2500 hertz, i did test this! police cars built by ford are putting them at harms way. the busses ford and gm built are in the same issues. *tr
