| Check | Why it matters |
|---|---|
| Voltage | Marine and vessel systems may use different supply voltages |
| Wattage | Affects light output, heat and fixture load |
| Base and contacts | Bayonet contact count and pin offset must match the socket |
| Envelope size | Must fit inside the navigation light housing |
| Approval needs | Regulatory or vessel requirements must be confirmed by the buyer |

Ordering a bayonet bulb without checking contact count.
Assuming all marine bulbs carry the same approvals.
Ignoring fixture space and lens design.
