Nav light bulb
Pre-season checks on Seawolf produced fzztpop when I switched on the white all round light on top of the A frame. I have no idea what type of light fitting it is, and there don't appear to be any identifying markings on it. The bulb is about the same size as a sidelight bulb in a vehicle, but it has two terminals on the base not one, so I've failed to find one locally (all the similar single filament bulbs in vehicles seem to be a single pin on the base) and I can't immediately see something like it online - but I don't know what you would call the bulb fitting pattern - can anybody advise please?
Secondly, the bulb is only 6 watt, and assuming it is a standard type and I've just missed it so far, I wondered what sort of wattage it is safe to uprate it to to increase visibility. I considered LED, but they seem to have issues too and I don't use it much, so have discounted that. I don't need or want to change the unit, but I wondered how many watts you could safely put in a relatively small fitting, have seen issues with melted Land Rover brake lights over the years with 21w bulbs in something that is a similar physical size, so I'm guessing 10-15w would be about the max?
Pics of the bulb and the fitting attached.

I'd be much more confident in an LED than filament especially if rarely used. What is the current path? Pin>filament>pin?

Thanks, I assume the two terminals are connected to the filament and the body is electrically separate but as it is blown I can't be sure.

Still looking, but I now reckon the fitting is called a BA15D type -

Have found some 12 watt ones on eBay so hopefully they will turn up!

eBay? Shouldn't that be MareHarbourBay down there? ;-) (Sorry, that was bad! lol. But happy memories of 6 months down the Falklands).

Having now fitted a 12W bulb in place of the original 6W, the white all round is much brighter. That is of course stating the blindingly obvious ... but as an almost free upgrade I would very much recommend it rather than just replacing like for like.

Have you checked the wiring can handle double current? 1amp vs 0.5amps

I can recommend these. Had one for a couple of years with no issues, low power consumption, a very bright light, and no change of light fitting

I didn't, but I honestly doubt it will be an issue unless the boat was wired up with something really puny, in which case physical durability would be as much of a concern. Typical lightweight wiring is probably good for about 5 amps.
