Below is an illustration showing how the red-green lens assembly uses a gasket to keep out water from the interior of a combined red-green sidelights navigation lamp made by PERKO and often used in mid-1980's Boston Whaler boats.

Re: Gasket for PEKO Red-Green Lens in Navigation Lamp
OLDKENT--Many thanks for the excellent illustrations. You have revealed some great details of the very commonly used red-green combined sidelight lamp often mounted at the bow of Boston Whaler boats. This thread is a good example of the purpose of the website: to collect and organize information on the covered topics.
I am very impressed with the vertical mounting of the miniature electric light bulb. I think that is called a Festoon bulb, or more precisely, a double-ended 12-Volt Festoon bulb. The vertical orientation of the bulb filament should produce very uniform lighting over the range of horizontal arc (12.5-degrees on each side from dead ahead) in which the light is to be shown.
PERKO is known for quality navigation lighting.

In the above publication, the Festoon bulb noted as "FIG. 71" can be found on page 65.
