Embarking on a restoration project for a classic 1955-1959 Chevy truck is a rewarding endeavor, and ensuring all your lights are functioning correctly is a crucial part of that process. One often overlooked yet vital component is the headlight switch. This article will guide you through the basics of Installing Head Light Switch in a 55 59 Chevy Truck, covering its function and importance.
Understanding the Headlight Switch in Your Classic Chevy
The headlight switch in your 1955-1959 Chevy truck is more than just a simple on/off button; it's the command center for your vehicle's lighting system. When you turn the knob, you're not just activating your headlights; you're engaging a complex series of electrical pathways that control multiple lighting functions. This includes:
- Headlights (high and low beams)
- Tail lights
- Parking lights
- Dashboard illumination
- Sometimes, accessory circuits
The proper function of your headlight switch is paramount for safety, especially when driving at night or in low-visibility conditions.
The physical switch itself typically has several positions, each corresponding to a different lighting configuration. For example, a common setup might include:
- Off: All lights are off.
- Parking Lights: Activates front parking lights and rear tail lights.
- Headlights (Low Beam): Engages the low-beam headlights along with parking and tail lights.
- Headlights (High Beam): Activates the high-beam headlights, and usually, the dashboard illumination intensifies.
Understanding these positions and how they relate to the wiring harness is essential for a successful installation.
Replacing or repairing the headlight switch on a 55-59 Chevy truck often involves working with older wiring. It's important to identify the correct wires and their corresponding terminals on the new switch. A wiring diagram for your specific truck model is an invaluable resource. Here's a simplified look at some common terminals:
| Terminal Label | Function |
|---|---|
| BAT | Battery power in |
| ACC | Accessory power |
| LP | Parking lights |
| DIM | Dashboard illumination |
| HD | Headlights |
This table provides a general overview. Always refer to a detailed wiring diagram for your year and model to ensure accurate connections. Ensuring correct wiring is critical to prevent electrical shorts and damage to your truck's electrical system.
