Re: turn signal indicators

Another possibility could be a bad ground to the indicators themselves. 
Since they are mounted in wood on later cars, they really need a good 
ground. If the ground is bad, the flow needs to go someplace to ground, 
so it flows back through the other bulb. This has happened to me on tail 
lights and front lights on my bad weather vehicles and my trailer in the 
past, causing the lights to blink in odd  sequence when the brakes are 
applied..
