Which LED bulbs for masthead, stern, and bow lights on H240?

Got my cabin bulbs replaced! Thanks to everyone for your help.

Now I'm on to the nav lights. I'm hoping to order the bulbs before going to the boat storage. I'm looking at the marinebeam site at these 31mm bulbs:

Perko Atwood Hella 31mm Festoon LED Replacement Bulb

1-1/4" (31mm) festoon bulb with wide beam angle for combination bow lights and masthead steaming comboHella 2010, 1181DP0CHR, 1184DP0CHR, LED, perko all round, perko combo, perko running light

I also saw someone else post that they used these, but I think it was for an H26:

30-LED 42mm Cone End Festoon - Mini-Max (FS-42-30C)

Marinebeam LED Lights for Perko anchor lights and navigation lights using Perko 0070DP1CLR Festoon type bulbs. This LED also replaces 10W SV8.5 festoon bulbs found in many small Hella fixtures. NOTE: This bulb also replaces CONE END Aqua Signal Series 25 bulbs for fixtures manufactured after...

Can anyone confirm the bulb? Is it the same bulb for all four?

Thanks!

PS - I do see on their site that they show two different bulbs for the two-bulb masthead light. However, I'm still trying to confirm if these 31mm bulbs are the right ones, or if I need the 42mm ones above.

Primarily I just wanted to know if the 240 has 31mm or 42mm festoon bulbs. The info on marinebeam seems to suggest that it's likely that the fixtures take a 31mm bulb, so I took a chance and ordered those. I'll post here if that is correct so folks can find that in the future.

Update: It turns out the stern and bow nav bulbs are 42mm, and the mast bulbs are 31mm.
