The car is telling you that you have a burnt out bulb. The faster blinking is another indicator of a burnt out bulb. It could be a faulty relay but you better make SURE all (I think three maybe four) turn signal bulbs are good.
You are going to have to turn on the blinker, walk around the car and find the bulb...
How does something immoral, when done privately, become moral when it is done collectively?
Furthermore, does legality establish morality?
Slavery was legal; apartheid was legal; Stalinist, Nazi, and Maoist purges were legal. Clearly, the fact of legality does not justify these crimes. Legality, alone, cannot be the talisman of morel people. - Walter E. Williams
