I was on E-bay a month or so ago and cant remember how I found this product, and can't find it since. I think it was called a turn signal synchronizer. I remember it showed a picture of a 97 crown vic rear tail light which flashed the left turn signal by right buld to left bulb in the tail light, hence synchronizing the light.

I saw the sync. for mustangs & crown vics only..Anyone ever heard of this? :eek7:

Found it, they are called sequential signal lights

I haven't seen sequential turn signals in years! They were standard on certain Ford/Lincoln/Mercury cars in the late '60s - early '70s. Each turn signal had 4 or so bulbs. The signal started by lighting the bulb furthest in, then the next one, and so on until they were all lit. It looked really cool. I'm surprised cars with that feature aren't more popular to restore!
