Back when LED bulbs were made up of several little lamps pointing in different directions, they weren't so good - it took 50 or more to make a decent bulb.
Now there is Surface Mount Technology, wherein the little flat dice are put on circuit boards. They are much brighter and the ones I mentioned make a good replacement for the tungsten bulb.
Automotive bulbs are blueish, but you can get "warm" bulbs as well. I cannot read with the overhead light no matter what bulb is in them, so I installed little swiveling directional lights that came with 10 w halogen bulbs. I have replaced these with 2 Watt MR-11 base LED bulbs, and they are very good to read by. These bulbs can be purchased in cold white or warm white, the latter has a color temperature of 3000K or so and are pretty pleasant. I don't mind the cold white, I find it good to read by.
I have an AquaSignal series 20 anchor light, and it takes a BA9s base, the small (9mm diameter) bayonet mount with a single contact. I found a nice SMD LED replacement so I am good on the anchor light for about 10 bux.
LEDs have come a long way. I am starting to use them in the 120 VAC circuits as well. I have not yet seen one fail, and perhaps I can someday get away with few or no spares....
