Well, that's the problem. Some of the LED's have a narrow viewing angle (45 degrees or less) and some are much wider. The more you look around, the more variations you find.
In the case of the 194 marker lights, I'd look for something that is a combination of a wide viewing angle and yet not terribly expensive. This is probably not a very critical application.
Stop/Turn/Tail (STT) are a different matter. I would suggest examining your existing STT fixture to see what what the existing viewing angle is, and then try to find an LED that offers similar properties.
One other small problem... license plate lights. Remember the need to use the same color LED as the lens (except of course, you can use any color LED you need behind a clear lens.) That suggests a minor problem with the fixtures that are common on our TT's that use the same clear incandescent viewed through a red lens for STT, but have a clear panel in the bottom so that the clear incandescent bulb also shines white light down on the license plate.
My thought is to get a small LED license plate light, and install it so that it shines on the plate, and then block the red light coming from the STT, problably with tape or maybe even paint.
Lode may be able to "shine" some additional light on the matter (I could not resist...
All of this suggests that swapping out the complete fixture has an advantage as they would function properly - the right LED behind the right optics. But that has an increased price tag attached.
And in the case of the Bargman 68 clearance lights, there is no exact LED version available. There are, however, a number of other clearance light fixtures that are similar in size and mounting that are availabe in LED versions and would completely cover the existing holes, etc. Or swap out the 194's for LED versions which is what I will do as the 194's burn out.
