The reason for me putting in LED is to have less electrical demand and extended EV driving and increased MPG. Thus I do not desire to put in resistors, as this would draw a similar current to the original bulb, and defeat the purpose. My LED's that fit the original bulb socket are LED arrarys with either 24 or 32 super-bright LED's that are at least 80% as bright as the original part, and much brighter than cars of the 60's and 70's still on the road, so appear "street legal" although there is no such claim on the package.
