Does anyone have a source for 24v LED replacement bulbs for 1156 & 1157 style bus bulbs? |

Those are also automotive bulbs. 12V dual filament. Assuming you have a 12V bus, you can buy automotive LEDs in white for $10 bucks each at automotive supply stores...PartsAmerica (old Advance Store), Autozone, and most motorcycle shops. Red is cheaper at about $6 bucks.
They are becoming pretty common...I suppose the area you live in may have some bearing on supply?
We even have "dancing" LED tailights. The LEDs run around in a figure eight pattern. Cool.
If you don't find them, let me know and I'll be happy to get them for you. 12V only for bulbs.. Plenty 24V LED complete light assemblies. |

I know about ten people are going to jump down my throat about this, but I have to say it anyway:
Bear in mind that these "1156" and "1157" (quotes very deliberate) so-called "replacements" are NOT street-legal. It is unlikely that you will be stopped, but you should know that you can be stopped and cited.
This is as opposed, for example, to a purpose-built LED lamp assembly that has been tested and certified to SAE standards.
The technical reason behind this is that your lamp housing has been designed, tested, and built for an incandescent filament bulb that radiates light in many directions, and the optical characteristics of the lamp/bulb assembly, including the reflector, are calibrated for this use. Putting an LED cluster, which emits light in essentially only one direction (with a slight fan-out for "wide angle" models), in place of the filament bulb means the lamp housing may no longer be achieving the design goal.
The simplest way to visualize this is to look at some of the automotive tail light assemblies, where a single bulb achieves both the rear-facing tail light function, and, at the same time, the side-facing marker-light function. Clearly, in this application, an LED cluster would not meet the required luminous intensity to the side for the marker light requirement.
Similarly, depending on the design of your tail lights, LED clusters may or may not meet the optical requirements, including off-angle visibility, of the federal and state lighting requirements.
(You will note, by the way, that SAE-approved LED lamps have various Fresnel optics built into the lens assembly to ensure that the required amount of light is available to off-center viewers.)
When you get your LED clusters in the mail, if they are in the original packaging, you should see clearly marked on the package "Off Road Use Only" -- this is the manufacturer's way of dodging liability for you putting these bulb replacements in your on-street vehicle.
When you deliberately put these in your 10-plus ton coach and operate it on the public roadway, YOU are accepting the full liability.
(The SuperBrightLEDs people are very cagey about this -- there is one small note at the bottom of one information page: "For aftermarket use. May not comply with SAE or U.S. DOT standards." They've changed the "Off Road" wording to "aftermarket", I presume to avoid putting off any otherwise suspicious buyers.)
FWIW.
