Swift Diary: High Mounted Brake Light Pulser/Flasher Installation

Brake light pulser/flasher/attention module is a small circuit which when connected to the rear brake light pulses the brake light every time brake is applied for a few times before keeping it lit steady. This circuit is usually connected to the center high mounted brake light (or the third brake light) of the vehicle.

The pulsing light pulsing grabs the attention of the driver behind you and giving him that fraction of a second to react earlier and stop safer. I think its a worthwhile addition to your car for the little money it costs.

There are many available and I bought mine from Mr.BrakeSafe; it is compact, has the delay feature, comes with terminals for solder free connection and priced just about right. Buy a model with a delay feature, which means if you have to repetitively apply brake in traffic frequently (within 2 secs) the light would light up steady instead of pulsing. Installation is simple and as given below. Please click on the photos to enlarge them.

Mr.BrakeSafe - The PCB and details of what goes where

Posi-Tap Connector allows you to T into wires without cutting them

Open the hatch door and undo these two bolts to pull out the center high mounted stop lamp from outside. Do not lose the rubber gasket aka washer on the end of the studs coming out of the plastic. To remove the connector from the brake light press down on the area marked with a sharp object like a forceps and pull the connector out.

Cut the green wire and strip the insulation using a wire stripper (or very carefully using a pair of small scissors) and crimp the terminals on the wire. Make sure they are secured by pulling on the terminal. If it slides out you need to do it again. Use a crimping tool for best crimp, you can also use pliers if you know what you're doing.

Remember Yellow lead from the PCB goes to the light and the Red lead from the PCB goes to the vehicle harness. Posi-Tap the Black to Black. Once done secure using cable ties or similar
