when riding I sometimes feel the need to make people aware of my presence so i'd like to hook something up on my bike. a normal biycle horn would do but i always like to try the harder route ( so i learn somethin) harborfreight sells a pack of 2 12v electric horns one high and one low. i would use only one. could i possibly use the 6v white wire with a push button switch? i'm assumign it wouldnt be as loud. thanks.
