A smaller dim one and a bigger brighter one.
I agree. I probably would have kept the Zevo bulbs if it weren't for the cold spot. The Zevo design works well to not blind the driver behind you, but there still needs to be some rearward-facing light in our corner taillight housings, just not a lot of it. A lot of LED bulbs have a dome lens on top to really project the light. That's something that should be avoided in our cars.

Matching the brightness of the incandescent bulbs on the low circuit is even more important on our cars because those corner lights are right next to the decklid LED panels.
