So, how much money did you save when you bought your vehicle? You did get the Bose radio system, Power Steering, power brakes, AC, TV, 8 way power seats, rear view camera, back up alarm, automatic parking assist and so much more but you didn't get signal lights. And I thought that all auto makers were required to have signal lights on all vehicles in the USA. That being said, why don't people use the signal light when turning or changing lanes? I know people that have had their vehicle for several years who use their signal light on a regular basis, and have never had to replace the bulb of the signal light switch. Using the signal light does not cost more money to run the vehicle. It's not like one forgets. If there is a police officer in front of or behind, we seem to remember. Signal lights are placed on a vehicle for one purpose; to save lives. Get in the habit; you won't be sorry.
