# Industrial Specification: Warning Light Array

## 1. Technical Definition
A cluster of indicator lights within a gauge cluster that visually alerts the operator to specific vehicle system statuses or faults.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **2.7-5.5 VDC**. Failure boundary: **LED junction temperature exceeding 125°C or forward current exceeding 20 mA**, Mechanism: **Thermal runaway due to positive temperature coefficient of LED forward voltage, causing current density concentration and localized overheating**.

### 2.1 Analytical Physics Model
Governed by the **Joule Heating & Thermal Resistance**:

> **Primary Equation**: $P = I^2 R = \frac{V^2}{R}$  
> **Engineering Impact**: Governs heating element sizing for shrink tunnels/sealers.
