I think they are as bright, but as with all leds, the light is more concentrated in one area, whereas the incandescent bulb lights in all directions, taking advantage of the reflector in the housing. This was a concern of mine, but checking in bright daylight satisfied my question on visibility.
These are plug and play. The led lights terminate in connectors the factory harness plugs in to. The load resistors as mentioned, stick to the inside of the light opening and are terminated in pin connectors, so the light can be removed if necessary, by unplugging them. This mod is completely reversible with no tapping into the factory wires.
These lights use the factory bulb, connector and all for the reverse lights. The back side of this light looks just like oem, and they twist-lock into place just like stock.
