I seem to remember if you install with the red wire not cut, all the LED's are on when the lights are turned on and become brighter when the brakes are applied.

When the red wire is cut, the upper and lower LED's are separated like the stock light, bottom side on with headlights, top side on with brakes.

If using option 1, uncut wire, you need to modify the separator for the wire to pass thru.
