When my trailer is connected to my vehicle, the turn signals are dim and flashing rapidly. What causes this?
When you add trailer lights to a vehicle system, the turn signal amp load basically doubles. Most vehicles have a flasher that controls the blink of a turn signal. The standard flasher provided in many vehicles will not handle this extra load. You should replace your flasher with a heavy duty flasher (8 to 10 amp) and make sure the vehicle engine is running. The flasher will slow down your turn signals and a running engine will increase brightness of the lamps.
