Question for those that added their own, How did you wire them? Do they light up when the brake is pressed or only when the turn signal is on?
The ones I have done are hooked to the brake lights- you can use some logic circuits for turn only, but it really isn't worth it. If your rig already has mid mounted clearance lights, you can move the ground for them to the running light circuit, which will let them blink both if the clearance light are on or not (clearance lights on, the ground for the clearance lights is through the turn signals, clearance off, the ground for the turn signals is through the clearance light circuit. This will not work with LED bulbs, without external diodes).
