Thread: 211-2 vs 578 - same sausage, different wattages?

    Default 211-2 vs 578 - same sausage, different wattages?

    Various bulb lookups suggest the dome light bulb in my '02 Silverado may be a 578 or a 211-2.

    Near as I can tell, they're physically the same bulb, with the 578 being 10 watts and the 211-2 being 12.5 watts.

    The Zevo versions appear to be the exact same "bulb" in two differently-labeled packages.

    Or am I completely wrong, which is often the case?

    You're correct about all of it: physically the same, 2.5 watt/3 candlepower difference, and while I haven't looked specifically, it's probably true that these "two" Zevo bulbs are really one and the same. There's a lot of that in the Zevo product line (1157, 2057, 2357, 7528...or 168, 194, W3W, W5W...or 3057, 4057, 3157, 3457, 4157, 4114...multiple different packages for the same Zevo LED bulb)

    Thanks, Virgil! What a crazy world we live in.
