Does anybody really know what ever happened to sequential turn signals?

Was it that people didn't want to pay the extra cost for a frivolity?" Well, OK, a couple- three questions. :-) Discussion ensues. :-P > There are a couple of > lighting wizards over there that can fill you in on all of the rules and > regulations regarding automotive lighting. > > If you want to start a real flame war, ask about red vs amber rear turn > signals. I'm not worthy - mine are red, and there's nothing I can do about it. :-) (1986 Fiero GT) http://www.abiengr.com/~sysop/images/GoldenFiero.jpg Thanks! Rich |

Does anybody really know what ever happened to sequential turn signals?
I don't know about their legality on new cars (paging Daniel Stern...).
The original electromechanical implementation on the mid-60s Thunderbird and late-60s Cougar tended to be a bit of a pain as it got older, and was rather daunting to troubleshoot unless you are familiar with how it works. See for instance http://www.tbirdranch.com/sequencer.html Of course, they ran *all* the rear lamps except the white ones through the system. One component, the stop lamp relay, was much more of a single point of failure than its name would indicate, and at least on Birds, is sometimes found in the "before" stage of restoration with its contacts not just pitted but completely vanished (which admittedly is mostly a testimonial to an inadequately spec'ed part -- there are a *lot* of light bulbs back there). Nowadays you'd doubtless do some or all of this with solid-state switching. And then you've still got hazard flashers (w/ two different wiring schemes depending on whether the switch is in the optional overhead console), front turn signals, and (in case you aren't thinking it's kinda over-the-top already) a current-sensing relay to make the fender-mounted turn-signal indicators double as a bulb-out detector for the rear. Their "Unique in All the World" motto also describes what the previous owner of your car may have done to make some or all of this sorta work once again. Sure is purdy as well as unequivocal when it is working, though. You get cooperation in lane changes and respect from tailgaters as in no other car when the Main Street Electrical Parade back there kicks in. (Good thing too, since a passenger-side mirror that belongs in a makeup compact was optional and a blind spot that could conceal a Macy's Thanksgiving Parade balloon was standard equipment.) Around town you probably get noticeably dimmer headlights too. --Joe |

Same reason you don't see cars with the attractive and/or distinctive styling of, say, the '64 T-bird (which had sequentials) or the '62 Imperial (with free-standing "podded" headlamps) anymore. Cars today are pretty much lowest common denominator transportation devices. For what its worth, sequential signals aren't illegal, and there are several groups that sell fully electronic sequential mechanisms for old T-birds to replace the electromechanical gadgets that originally came on them. They can be applied to any car that has 3 individual taillamp sockets in a single housing- I've seen them used on 90s Impala SS's for example. In fact, one of the guys that sells sequential electronics developed his kit explicitly FOR the Impala SS. |

There is a company on the web which makes electronic sequential taillight
units. http://www.webelectricproducts.com/ Just because someone makes them doesnt necessarily mean that they are legal anywhere. I have no idea of the legality. They were very eyecatching years ago. |

Ah yes, the MMobile. For years the Imperial was specifically banned from Demolition Derby competition, as no other vehicle stood a chance against it. |

I didn't know that but am not surprised. Aside from the sheer size of the thing, the Imperial kept body-on-frame construction for several years after almost all the rest of the industry, including other Chrysler models, had gone to unibodies for their passenger cars. Not until model year 1967, I think, did the Imperial go that route. --Joe |
