Your Challenger goes from 60 to 0 in 110 feet !!. Will the driver behind you be ready to stop when you do? The BLP-1CH pulser module can give you the extra measure of safety you need. These devices are full "Plug-N-Play" harnesses that simply plug into your existing Center High Mount Brake Light. There are no wires to cut, and no adjustments to make.The module automatically pulses your third brake light when you apply your brakes. The light will pulsate on and off for about a second, then stay on steady for as long as you press the brake pedal. The unit is designed to create a gentle fluttering of light, so your car is more noticeable, yet it doesn't aggravate the driver behind you (notice how you can see it flashing, even while reading text down here!).The "Delay-Repeat" circuit means the brake lights have to be off for at least 15 seconds before the cycle can be restarted. So, if you are in bumper-to-bumper traffic, the brake light isn't always pulsing.
