    Is there an easy way to wire up a hazard switch to my lights? I have a 1960 and it did not come with them. I've been in the way quite a bit the last few days and if it happens again I don't want to get rearended. Could a switch be wired to the relays? Is it that simple?

    There are kits, including factory accessory ones for early '60's Chevies I know, to install hazard lights. Basic circuit is simple and could be made from junkyard stuff--an extra flasher (steal from fusebox of late '60's or 70's car with number of bulbs similar to yours) rated for all the signal bulbs instead of half of them, a fairly high rated switch, and some wire. Basic circuit is power wire (from direct bat circuit, NOT ignition or accessory) and four wires to the four lines to car's turn signals. I'll have to look at a switch from one of these--I think special switch may well be needed as I mull over this, since those four wires need to be separate when switch is off so they do not link your brake and turn signals when hazards are off.
    If you have access to a junked car like yours, cleanest install would be to cut out the set of multi plug connectors that connect steering column wires to the car and use the pair to snap your new wires right into that connection like a factory hookup.
    What's the car in question?

    If I'm not mistaken, you used to be able to buy kits at NAPA through the NAPA Lighting books. I know they had kits that did the whole shebang, blinkers and everything, but I seem to remember a kit for just hazards too. Check it out.

    No its not that simple.

    Your turn signal lever controls 2 things at once. It connects power to the relay and selects between left and right light circuits. You need a seperate relay to bypass the lever.

    Wait a minute--what are we discussing here? A 1960 what?? There shouldn't BE any relays in a signal system of this age.
    The issues will lie in keeping the circuits separate when hazard switch is off, as the signal switch both selects side and disconnects brake light on that side on any 1960 vintage American car I can think of.

    What about the flasher? That's a relay.

    You could add a double pole double throw switch in place and add another flasher.

    Normally a separate flasher is used since it will be flashing twice as many filaments as the turn signal one. Multipole switch would be necessary to keep from mixing brake signal with turn signal with switch off--easiest source of switch would likely be a kit...

    Getting too complicated--get a flare or thermite grenade or something.
     
  10. Or just conect a switch and flasher relay after the brakeswitch to the brakelights, its not gonna flash in front but its pretty rare to be rearended in the front...

    It's a 1960 Ford Fairlane 500.
    I don't know if that would be good to drive down the emergency lane real slow and erratic with flares all over the car. :eek: Could be fun.
