Cab light into a third brake light

[jkk]

Hey guys
Thinking about turning my cab light into a third brake light keeping the clear lense just adding a red bulb or led

Anyone done this or have any ideas on the best way to hook it up?

Heres something you can do if you want to keep your cargo light . Center is red led and the 2 outer lights are cargo but not led . If I remember correctly this style if from a 90's truck . The hole will have to be trimmed with a dremel but fit pretty well .

I hate eliminating something to have another . Cargo light does come in handy at times .

As said above , just tie into the brake circuit under the dash with a new wire . Seems like I tied mine into the circuit at the brake light switch . You can not use the wires there . Interior light still uses them . You could clip the wire at the cargo switch that goes to the cargo light if still planning to use the oem light for the +12 from the brake switch . The ground on the cargo light will have to be removed from the door circuit and grounded independently .

I did this 2 weeks ago on my 87, easily done.
Just ran a wire from the brake switch up thru the cab to the cargo light, connected this wire to one side and grounded the other to the cab.
I bought a RED led globe and it works great.
