Hi Bill The OEM tail light is smaller than the more powerful brake so you cannot mix up the wattages. You'd find it tough to find a higher wattage bulb with the same fitting. And of course the tail lights do not have mirrored reflector unlike the other lights - correct? I agree though, they are pretty pathetic. Anyone try one of these Neon headlight illuminating lights you can buy off ebay? Should be dead easy to try at least.
