Does anyone know how to make the high center stop light blink while brake is applied 2003 F-150

 

If you want to install a back off modulator for a motorcycle inline for the center high mount brake lamp, that is an option.

The two that come to mind are :

The Kriss unit :

The other one that seems to be popular with the Concours riders is the Back Off modulator from Signal Dynamics. They make this unit for auto applications :

You would install this in the rear panel, using the brake wire to the high center mount stop only for your application, rather then at the source of the brake under the dash causing all 3 brake lamps to do this function.

You might be able to find other mfgrs of these at any local motorcycle shop.

Let me know if you have any other questions, or might need the wiring diagram for your center high mount brake lamp.

Good luck

 

Thanks for the reply I'll keep you posted
