MN 13.5-0.16

Which parameters define its operation?

Compared with ultra-miniature SMN indicators, this lamp has a larger bulb and substantially higher light output. It is intended for applications that need visible local illumination rather than only a luminous point behind an indicator lens. The electrical rating should be considered together with light output and operating duty. Overvoltage raises filament temperature and will normally shorten service life.

How is the lamp constructed and installed?

The bulb is approximately 12 mm in diameter and the overall length is about 24 mm. The E10/13 screw base provides replaceable socket mounting without soldering. The reference mass is approximately 2.5 g. Before installation, compare bulb diameter, overall clearance and the exact connection method. The lamp must not be forced into an unsuitable holder, loaded through the glass envelope or fitted by changing the original mounting arrangement.

Where is this execution used?

Lamps in this group are used for local indication and illumination inside compact instruments, annunciators and illuminated controls. Installation in a particular aircraft, helicopter, panel or instrument must be confirmed by the applicable parts list or equipment documentation. The SMN or MN family name alone does not establish aircraft applicability.

How should the correct lamp be selected?

Confirm the 13.5 V supply, 0.16 A load, E10 socket and available clearance. The similar MN 26-0.12-1 uses the same base size but is designed for 26 V and is not an electrical substitute. Related products on the card help compare nearby executions in the same narrow subgroup; they do not establish automatic interchangeability. An enquiry should include the marking of the removed lamp, circuit voltage, holder or lead type and the required quantity.
