    Description

    Headlight relay kit converts the 1967-68 Mercury Cougars with quad or 4 headlights to modern car technology. If your Cougar suffers from dim headlights you are not getting a full battery power to the back of your headlamp bulbs. Safe for use on our vintage cars. Still uses your headlight switch. Instead of carrying reduced voltage to the headlights through the switch, the switch triggers the relay, which takes power directly from the battery. This relay Kit can handle the higher wattage bulbs (up to 100W) which is used outside of the USA. Included in kit: Two weatherproof controllers, one 40A auto-reset circuit breaker, power wire, crimp-on connectors and easy to follow instructions.

    Benefits:

    • Easy to install, and no cutting. Plug in the controllers, run a power feed and you're done. 
    • Redundancy. Each headlight - High, Low, Left, Right has it's own relay and each side has it's own controller. 
    • Each 40/60 Amp 12 Volt sealed relay has Negative Spike Protection built in. This means no spikes or feedback to upset delicate electronics. 
    • Each controller contains an internal auto resetting circuit breaker to isolate left and right sides. 
    • If a controller goes bad, the other controller will continue to power the other side. 
    • The single feed wire is easily hidden and the controllers can be removed for car shows if desired. 
    • Compact size - each controller is only 3"x2"x1.5". 
    • Kit comes with a 40A auto resetting circuit breaker to power up to 4 halogen lamps at 10A each. 

    Note: It is the responsibility of the purchaser to ensure that the headlight wiring is sufficient to carry the amperage required by the installed lamps.

    Very nice item, true plug and play. The gauge of the power wire is definitely big enough. Im sure they made the old sealed beams a bit brighter. I've since replaced the main beams with H4 headlights and feel much better knowing the extra amps aren't running through the headlight switch, plus I can actually see at night.

    The only bad thing I could say is the supplied plug for the drivers headlight isn't big enough for the gauge of wire.
    These really can be easily hidden.

    This kit should have been a factory standard. The kit is easy to install, no mods to existing wiring is needed. With the kit installed halogen headlamps or a headlight conversion kit can be installed.

    Really thorough and well-thought out kit. More heavy gauge 12V lead than needed, but that sure beats the other way around. Nice workmanship! Two days from the opposite corner of the USA was pretty cool non-premium shipping, too.

    Question
    Asked:
    I'm looking at the Halogen Headlight Conversion kit. The kit appears to have a single relay vs the two relays in this kit. Is there a reason?
    April 23, 2022 9:34 PM
    Answer
    WCCC Admin Answered:

    It all comes down to what wattage of bulbs the systems can handle.

    Per the product description:

    This relay kit can handle the higher wattage bulbs (up to 100W) which are used outside of the USA.

    The Halogen Headlight Conversion kit (ITEM #: 30086) comes with the 'mini' relay system which is designed to handle around 200 watts total split between the 4 blubs, whereas this listing is for the 'full' relay system which can handle up to (4) 100 watt bulbs or 400 watts total.
