way to keep turn signal bulbs "on" so they're brighter?

[hedpe]

Hey guys, when i went to clear corners on my 500E, i also put the clear bulbs in. Thing is, they're not as bright as my headlights, they look extremely dull. But when they are flashing, when the flash is "on" the bulb is as bright as the headlight. I remember reading somewhere tweaking it to have the bulbs be "on" as bright as they flash, and when you turn your turn signal on, then they dim and go back to on, and dim, and back to on, for signaling. Anyone know where that thread is or how to do it?
