The price per is much higher than a 150ohm 2 watt, for sure (0.20 cents per vs 0.69 cents plus shipping). Also will a 5 watt draw more current as well? I'm not sure what else is 'down/up' the line here, remember the BCM makes the ground on these doesn't it? Its just a cautionary bit of advice, the mod is to keep the lamp out indicator off, peeps will do what they want anyway. The cement ones, just how large are they? Whew....
