I've seen on various websites of these led replacement bulbs for the standard 1192? Interior bulbs? You can get them in pretty much any color red, amber, yellow, green, etc.? Was wandering if anyone has tried any of these bulbs yet? I think they are even making them now for the taillights too? Wandering if these are a cheaper way to go LED than the LED conversion tail light kit being sold or the kirbans dash lighting kit?
