Replacement for the 4.5" sealed beam can be gotten from Larson LED it takes a replacement of a Par 36s

Have a link?

Is this it?

Has anyone done this successfully? I bought a set from superbright and haven't been able to get them to fire yetis my 149. I think the problem is in my switch/wiring, but everything seems to be as expected with a volt meter. I need to put a test light on it. (The bulbs light if wired directly to the battery)

Remember those LED bulbs are polarity sensitive and if hooked up reverse they will not work

Yes, it's been done successfully. Check your polarity. Diodes only accept power in one direction.

I am aware of the potential for polarity problems, in fact currently I have one bulb wired each way to keep hat base covered. (They may have resolved the polarity problem internally with these bulbs considering they are sold as AC/DC and superbright is usually good about telling you when a bulb is sensitive to polarity)

They can't solve a polarity issue internally..... it's an LED. Light Emitting Diode. The very nature of it is polarity specific. You either didn't get DC compatible lights, or they are bad, or you didn't wire them right.
