The Toyota Alphard 30 series (AGH30), specifically the models from 2015 onwards, uses advanced lighting systems, including heat lamps integrated into its headlamp assemblies for certain high-spec variants.

Here’s a description of the 58–62 heat lamp in this context:

Toyota Alphard AGH30 (2015–present) — 58–62 Heat Lamp Description

Component: Heat Lamp (Part of Headlamp Assembly)

Location:

• Integrated within the LED headlamp housing (usually the outer section of the front headlights).
• ''58–62'' refers to the pin numbers or circuit designation on the headlamp connector, commonly found in wiring diagrams.

Function:

• Acts as a de-icing/defogging heater for the headlamp lens, especially in cold climates.
• Prevents fogging, condensation, or ice buildup on the inner or outer surface of the headlamp cover.
• Automatically activated by the BCM (Body Control Module) based on temperature sensors.

Technical Features:

• Low-power resistive heating element.
• Typically powered by a 12V supply, controlled via relay or ECU.
• Pin 58–62 may correspond to the signal or power supply lines for this heater within the multi-pin headlamp connector.

Associated Systems:

• Smart headlamp system
• Automatic headlight leveling
• LED/Projector headlamp module

Common Issues:

• Heat lamp failure can lead to moisture buildup or fogging inside the headlamp.
• May trigger headlamp warning light on the cluster if monitored.
• Connector pins 58–62 may show signs of corrosion or burn if water intrusion occurs.
