Running lights


Recommended Posts

When you have your running lights on that includes the front turn signals right? Are they bright or dim? when you click on the turn signals while having the running lights on dose the bulb go from dim to bright or bright to dim or bright to off or what?

On my late '74 the running-/turnsignal lights are combo bulbs with two filaments. One (dim)for the running lights and one(brighter) for the turnsignal function. On my car there are three wires from the harnass to the turnsignal units to service the two filaments in the combo bulbs. So when operating the runninglights, one filament gets constant power. The turnsignal filament only gets power from the flasher unit when you operate the turnsignals.
