Buying Guide
What to consider when choosing dashboard bulbs
- Base compatibility: Confirm your vehicle’s socket type (T5, T10, PC74, etc.) and required base size before purchasing.
- Voltage and brightness: Ensure 12V operation and judge brightness by lumen output or chip type (3030 vs 5050, etc.).
- Durability: Look for long lifespan (hours) and heat dissipation features, especially for enclosed dash spaces.
- Color preference: White vs ice blue can affect perceived contrast and gauge readability in daylight and night driving.
- Installation: Prefer plug-and-play kits with minimal polarity issues; rotate bulb if it doesn’t light up initially.
- Vehicle coverage: Some kits advertise wide compatibility; verify your exact model year and dashboard layout if possible.
