Convert cargo light to third brake light

[BGPick]

Anyone converted their cargo light to a third brake light? Almost been rear ended twice now because of idiots not paying attention. And I’m sure it doesn’t help that there’s only the two tail lights which are rather dim.

Thats one reason i added this and am gunna add the rapid fire LED tail lights soon as money will allow. All except 1 of my accidents i was rear ended, i like it to be seen back there.

Extra lighting may or may not help with the way drivers are today. FOMO is causing a lot of accidents and they probably won't pay any more attention to more lights that than they already do. Just hope it doesn't happen. Although, they are responsible for it if they do!!!

Yeah, I just fear that insurance would total the truck out depening on the extent of the damage. And in IL it’s near impossible to register/insure a salvage title vehicle. So better safe than sorry!

I imagine it’s just as easy as mounting it and then tapping into existing brake light wiring somewhere. Only problem would be making sure it doesn’t flash with the turn signals.

I’m thinking a train horn facing backwards and an on board compressor... I’ve wondered about this, too. The cargo light serves a good purpose, I think. I’ve also wondered about putting one on mine sometime in the distant future. Even though it’s not a pickup, if I wanted some light back there for whatever reason, I could just flip a switch. What about a Ford third brake light? You can keep the cargo lamp, and you can add the brake light.

I like the way you think, my friend!

Haha, the train horn or the brake/cargo lamp?

Fear Of Moving Over?

We suffer from that a lot in PA due to the the front platers.

I converted my cargo light, or rather modified it to be both a cargo light AND third brake light. I tapped into the brake light circuit. When the brake pedal is pressed...brake lights, when the turn signal is activated, turn signals. Now I have four brake lights out back and four turn signal markers as well.


What I did was run two individual leds, one on either side of the cargo light.

The individual leds which serve as brake lights are small red led side marker bulbs. The cargo light which was originally an incandescent was also swapped out to a led strip (white). It is a tight fit, but all three led lights fit snug inside of the housing. I simply wired up all three lights to their respective circuits.

I have a train horn (3 actually) on my other truck. The only thing it does is make people piss themselves AND swerve. It never seems to fail, but when my trailer is attached to my truck, every one drives like an idiot. I will admit however, I still get a kick out of how loud and disturbing that train horn is. It really wakes up drivers who aren't paying attention.

It will flash due to the circuit design. You may be able to wire in a seperate switch behind the brake pedal, but theres more work and wiring involved.

Here I was reading this and found myself wondering "Do I have a cargo light?"
Answer is nope.
Bummer.
Hopefully the huge steel bumper and tow hitch will make them pay attention.
Wishful thinking, I know...

I installed a third high brake light onto my other car and people still try to run me over often. Then they swear at me as they drive by and I am in my driveway.
People are idiots...

Now I am going to put aux. brake and running light options on my list of things to do before winter comes and people get really stoopid.

There is a circuit (WHT 17) that can be tapped into for a dedicated brake light signal (i.e. one that is unaffected by turn signal operation). It is short - the only accessible part is from the load side of the brake switch and where it enters the steering column - but it is common practice to use that WHT 17 lead to operate electric trailer brakes. After leaving the MFS that circuit is useless for a dedicated brake light power supply - because at that point it also supplies the directionals.
