Just as a follow-up I replaced the tail lights with the Camco LED Bulb. The LED bulbs are indeed brighter than even new filament bulbs, but not ridiculously brighter, like 130% brighter. The polarity on the bulb socket assembly was already correct for these LEDs so there was no alteration necessary, just plug and play. So all three brake lights, both turn signals, and tail lights are LED. Only the 4x reverse lamps are filament bulbs.
