Auto Parts Car Headlight Switch Assembly OE 30739305 for Volvo S80
-06 Lighting System
The Headlight Switch (OE Number: 30739305) is a critical interior
control component exclusively engineered for Volvo S80 models up to
2006 (S80 -06). Mounted on the vehicle’s dashboard or steering
column (per Volvo’s S80 -06 interior design), it serves as the
primary user interface for activating and adjusting the front
lighting system—including headlights (low/high beam), parking
lights, and often auxiliary functions like fog lights or instrument
panel dimming.
Constructed with a durable thermoplastic housing,
precision-machined electrical contacts (typically copper alloy for
conductivity), and a tactile rotating/clicking mechanism, this
OE-grade switch adheres to Volvo’s strict quality and safety
standards. Unlike generic aftermarket switches, its form factor,
terminal configuration, and function layout are identical to the
original part—ensuring seamless integration with the S80 -06’s
electrical system and dashboard. This eliminates compatibility
issues (e.g., non-functional lights, error codes) and preserves the
vehicle’s factory control logic, such as automatic headlight
activation (if equipped).
Core Functions
- Lighting Mode Control: Enables drivers to activate/deactivate key
lighting systems:
- Parking Lights: Powers the front side marker lights and rear tail
lights (for low-visibility parking or urban driving).
- Low-Beam Headlights: Activates the primary forward-facing
headlights (for nighttime or low-light driving, complying with
global road safety regulations).
- High-Beam Headlights: Toggles between low and high beams (for
long-distance visibility on dark, unlit roads), often via a
push/pull or separate lever integrated with the switch.
- Auxiliary Function Integration: In many S80 -06 variants, the
switch includes secondary controls (e.g., a rotating ring or
separate button) for fog lights (front/rear) or instrument panel
brightness adjustment—centralizing lighting-related controls for
convenience.
- Electrical Circuit Protection: Features built-in contact resistance
management and overload protection. The copper-alloy contacts
minimize voltage drop (ensuring full power to lights) and resist
arcing (which can damage the switch or vehicle wiring). If a
lighting circuit short circuits, the switch’s design helps prevent
excessive current flow, protecting the S80’s electrical system.
- Safety Compliance: Meets global automotive safety standards (e.g.,
ECE R10, FMVSS 108) for lighting control reliability. It ensures
headlights activate consistently in low-light conditions, reducing
accident risk, and its tactile design prevents accidental mode
changes (e.g., switching off lights while driving).
Compatible Vehicles
This Headlight Switch (OE: 30739305) is exclusively designed for
Volvo S80 models produced up to 2006. Below is the consolidated
applicable year range:
| Model | Applicable Years |
|---|
| Volvo S80 -06 | 1999–2006 |
Note: “S80 -06” refers to the first-generation Volvo S80 (produced
from 1998 to 2006). For 100% fitment accuracy, confirm
compatibility with your vehicle’s VIN (Vehicle Identification
Number) or Volvo’s official service manual—this accounts for minor
trim-level variations in switch functionality (e.g.,
presence/absence of fog light controls) across different S80 -06
variants.
