The 1970 Mercury Cougar, a classic muscle car, is known for its sleek design and powerful engine. But for many enthusiasts, the sequential turn signals are a defining feature, adding a touch of elegance and sophistication to the car's overall aesthetic. This article explores everything you need to know about these unique signals, from their original functionality and common problems to restoration techniques and modern modifications.
What are Sequential Turn Signals?
Sequential turn signals, unlike standard turn signals that illuminate all bulbs simultaneously, feature a "sweeping" effect. The lights illuminate one after another, creating a visually appealing, flowing transition from front to rear. This was a relatively advanced feature for its time, contributing significantly to the Cougar's distinctive charm.
Why are 70 Cougar Sequential Turn Signals So Popular?
The popularity of the 1970 Cougar's sequential turn signals stems from a combination of factors:
- Uniqueness: The sequential feature wasn't commonplace in cars of that era, making it a distinctive characteristic of the Cougar.
- Aesthetic Appeal: The sweeping effect adds a touch of class and sophistication, enhancing the car's overall visual appeal.
- Collectibility: As a sought-after classic car, original parts like these sequential turn signals become highly valued among collectors and restorers.
Common Problems with 70 Cougar Sequential Turn Signals
Over time, several issues can arise with these classic turn signals:
- Burnt-out Bulbs: The most common problem is simply burnt-out bulbs. Replacing them requires careful attention to detail, ensuring the correct type and wattage are used.
- Faulty Wiring: Age and wear can damage the wiring, leading to intermittent operation or complete failure. Tracing and repairing faulty wiring often requires patience and electrical diagnostic skills.
- Damaged Flasher Unit: The electronic flasher unit responsible for the sequential operation can malfunction, leading to incorrect flashing patterns or complete failure. A replacement flasher unit is usually needed in this case.
- Corrosion: Corrosion can affect the connections and components, especially in areas exposed to the elements. Thorough cleaning and preventative measures are crucial.
How to Restore 70 Cougar Sequential Turn Signals
Restoring the original sequential turn signals often involves:
- Inspection: Carefully inspect all components, including bulbs, wiring, connectors, and the flasher unit.
- Cleaning: Clean all contacts and connectors to remove corrosion. A wire brush and contact cleaner can be helpful.
- Repair or Replacement: Repair damaged wiring or replace faulty components, such as bulbs or the flasher unit. Using original or high-quality reproduction parts is recommended to maintain authenticity.
- Testing: Thoroughly test the system to ensure all lights are working correctly and the sequential pattern is functioning properly.
Can I Upgrade or Modify my 70 Cougar Sequential Turn Signals?
While preserving originality is important for many restorers, some enthusiasts opt for upgrades or modifications. Options include:
- LED Conversion: Replacing the incandescent bulbs with LEDs can improve brightness, efficiency, and longevity. However, ensuring compatibility with the existing flasher unit is crucial.
- Modern Flasher Unit: If the original flasher unit is beyond repair, a modern replacement offering improved reliability might be considered. This may require some electrical adaptation.
- Custom Sequential Systems: Some aftermarket companies offer custom sequential turn signal kits that might provide additional features or a different flashing pattern. However, this typically requires significant modification.
What are the Different Types of 70 Cougar Sequential Turn Signals?
While the basic concept remains the same, minor variations in lens style or housing might exist depending on the specific model year or trim level of the 1970 Mercury Cougar. It's always advisable to consult a parts catalog or a Cougar restoration specialist for accurate identification.
How Much Does it Cost to Repair or Replace 70 Cougar Sequential Turn Signals?
The cost depends on the extent of the repair. Replacing a single bulb might cost only a few dollars, while a complete restoration, including wiring and flasher unit replacement, could be significantly more expensive. Sourcing original parts may also increase the overall cost.
