I have a 1986 Outrage 18. I am in the process of replacing the navigation lamp lightbulbs but am having trouble determining the type of bulbs that should be used with respect to volts and watts. Another article on this site said that the [sidelights] bulbs were type 1152. What about the masthead and sternlight?

Usually a miniature electric light bulb will have some form of identification etched on the glass of the bulb, but it would not be surprising to find that really old light bulbs might no longer have it visible. Try a magnifying lens to see if you can find anything on the bulb or the base.

The voltage is nominally 12-volts. The wattage is a bit more critical. If you use a bulb with too much wattage there will be too much heat, which could damage the lamp lens, usually a thermoplastic. Use too low wattage, you won't get enough light output.

Unfortunately I do not have the originals. Currently in the masthead there is a 12v 10w bulb. To me it seemed to be very hot raising the concern of damage to the plastic. Although I think it is hot, the plastic may be designed to handle it. However, that is what is prompting my search for what the original volt/watt is for the navigation lights.
