Will this fit my light?
Will this fit my Perko Series 1127–1130?
Yes, in compatible Perko Series 1127, 1128, 1129, and 1130 navigation lights that use a BA15D non-index (level-pin) bulb. Match voltage and lens/bulb color.
Will this replace Perko Fig. 0374 / 374-4?
Yes, in compatible fixtures that use Perko Bulb Fig. 0374 / 374-4 (including 0374001CLR and 0374002CLR). 120V models on this page cover P374-4 NI applications.
Will this fit Aqua Signal Series 40?
No. Aqua Signal Series 40 typically needs a BAY15D index bulb with offset pins. Use Polar Star 40 for those fixtures.
How do I know I need non-index instead of index?
Remove the existing bulb and check the side pins. BA15D non-index pins are level and opposite each other. BAY15D index pins are offset at unequal heights. Need index? View Polar Star 40.

Frequently Asked Questions
Which LED color should I use behind a colored navigation-light lens?
Use a red LED behind a red lens, a green LED behind a green lens, and a warm white LED behind a clear lens when a color-matched LED is available. Matching the LED color to the lens helps produce the required navigation-light color and intensity.
Can I use a white LED behind a red or green lens?
Use a color-matched LED behind a colored navigation-light lens when a color-matched LED is available. A white LED may not provide sufficient energy in the required red or green wavelength range after the light passes through a colored lens. A color-matched LED produces the required color more efficiently and is the configuration used for navigation-light certification.
Why did incandescent navigation lights use higher-wattage bulbs behind colored lenses?
Incandescent bulbs emit a broad spectrum of light. Much of that light is blocked by a red or green lens, so a higher-wattage incandescent bulb may be required to achieve the specified visible range. A color-matched LED produces more of its output in the wavelength range that passes through the corresponding lens.
Are the bulbs certified by themselves?
Certification applies to the tested combination of LED light engine, navigation-light fixture, lens color, operating voltage, and installation configuration. Customers should select the correct bulb for the specific fixture and lens.
How do I identify a BA15D non-index bulb?
Its two side pins are directly opposite each other at the same height. If the pins are offset at unequal heights, the bulb is BAY15D index. Need offset pins? View our BAY15D index navigation LED bulbs.
