Couldn't load pickup availability
This LED bulb is a direct replacement for a GE89 Single Contact Bayonet, or a GE90 Double Contact Bayonet Bulb. These have BA15S and BA15D bayonet bases, respectively. Just be sure to choose your base type and bulb output color when ordering.
This small but powerful LED bulb exceeds the performance of the original incandescent, but uses 80% less power.
Fit check before ordering
GE89 or GE90 Bayonet LED Bulb should be matched to the existing fixture before ordering. The product name identifies the bulb or fixture family, but the final fit still depends on base, pin orientation, voltage, color, clearance, and the job the light performs.
| Check | Why it matters |
|---|---|
| Base or socket | G4, bayonet, wedge, festoon, MR11, and E26/E27 bases can look similar but fit differently. |
| Voltage and polarity | Marine DC systems vary, and some installations are sensitive to wiring, dimming, or polarity. |
| Color and use | Warm white, cool white, red, green, and dual-color options solve different cabin, cockpit, and navigation-light jobs. |
| Physical clearance | Tower, side-pin, back-pin, dome, and fixture housings can interfere with lenses or covers. |

FAQ
Can I choose by bulb family alone?
No. Confirm the exact base, pin direction or offset, lens clearance, and color before ordering.
Is every LED suitable for a navigation light?
No. Navigation lights depend on fixture geometry, visibility sector, lens color, and output pattern. Use a navigation-specific bulb or fixture where required.
