Combining tail/brake lights with signal lights.

[civic83]

I did it using rpm slash tail light buckets, I flushed them into the rear cross member, the main brake/tail LEDs are 5mm in the stock holes that come in the buckets, next I drilled a 3mm hole in the edge of each bucket and put the turn signals in there, so when they flash the tail light gets brighter just like if the brakes are applied. For the backup I just used an extra round clear lense and glued it to a piece of styrene tube to make the backup light.
