I don't like the way the brake lights in the tail light housing on the Firebird work. Each side has three bulbs, but only the two center most bulbs are brake lights (3057 bulb). The outer most lights are just tail/running lights (194 bulb).

I want to change the 194 tail light bulb to be a dual filiment 3057 so the entire tail light lights up with the brake or turn signal. It looks like all that it takes is modifying the 194 mounting hole to accept a 3057 base and wire it in parallel with the other 3057/brake/turn circuits.

Maybe even upgrade the 3157 to 4157K (kripton gas) bulb. A few more watts means a brighter light. And its a long life bulb.

Anone done this?
