Hi, I have a '78 450 SLC. The turn signals flash very quickly when engine is cold. Normally, quick flashing means a blown bulb, in this case, all bulbs are good, after the car warms up, the indicators slow to normal speed. Any ideas ?
Just got the new one today - works like a charm.On my old 67' 220D fast flashing meant that on of the bulbs was out. Maybe you have a loose or dirty connection to one or more of the bulbs.
