Bulb for navigation lights P28s-socket

We deliver only sealed marine light bulbs (for example, PB-PETRS & BEY)
with BSH (Federal Maritime and Hydrographic Agency) Certification (ZP-D1703/04).
These bulbs are a component of the certification of navigation lights.
Even spare incandescent bulbs located onbard must be approved,
so that the guarantee remains fully covered in case of damage.
