This is with only tail/running lights. Note, the LED Strip is a single intensity bulb array but the addition of a diode circuit allows it to function as dual intensity. When the brakes are applied, it is twice as bright! With Brakes

Later on, I modified the LED strip by replacing the existing strip with two smaller ones on the ends and a 9.5 inch in the middle. The middle strip is connected to the run/brake lines via a diode bridge circuit. All three LED strips are housed in the original plastic housing.

Still Later, I used the same concept and placed a flexible LED strip inside the OEM turn signal housings, powered them from the same Diode Bridge Source, and now have run/turn/brake functions from the turn signal housings.
