I use the BackOff XP module with my CHMSL (center high middle stop light). It has two flashing functions and I have wired it like this: When I apply the brakes, it flashes fast and then stays lit until I quit braking. When I am sitting at a stop light, I use my handbrake which makes the module flash slow then steady on then repeats slow flash then on. I may wire the inside brake lights to flash too .. but the outside brake lights will remain as wired. Highly recommended!

I think that three flashing brake lights should get the attention of someone behind me .. Plus I like advertising that my 25 year old car can have an advanced feature that others do not. another feature I added is a red pushbutton in the center console I can push to activate the brakelights to tell tailgaters to back off! rob
