Time to modify brake lights on my 2016 California T

I've now put in 1,100 miles on my 2016 Cali T since I got it a month ago. What an awesome driving machine.

Today was the 2nd time another driver mentioned about the brake lights.

1st guy was 2 weeks ago. He pulled along side me and said "You may want to check your brake lights as I dont think they are working.......... I just said Thanks, I will once I get home. Not enough time to explain the history of the car design.........

Went for a drive today, merging on to the freeway there was a car in front of me going a little slow. I see enough space for both of us to merge so we proceeded to merge to the freeway. A fire truck was on the lane we are merging to so I turned on my turn signals.

Fire truck did not slow down for us, got close to my rear bumper and honked his horn. I just waved and said Sorry!

He pulled along side and said - you should try and use your signal lights so that people wont run into you.
I said I did! He said "I sure as heck did not see any blinkers on". I said most likely because the brake lights and turn signals are located on the lower bumper. He said Well, that's a stupid design. I said I know, sorry.
No time to explain driving side by side on the freeway.

Time to fix this problem ASAP. For me its now a safety issue and I was trained in the military and aerospace industry that we fix safety issues ASAP.

I will start looking into what it would take to rewire the brake lights back to original design.
My idea is to cut the wire going to the rear fog lights, cap and stow that wiring. I never use rear fog lights.

Then, run a parallel wiring from lower bumper brake lights and hook it up to rear fog lights so that that light is now used again as brake lights and is in line of sight of drivers behind us.

If you have done this already kindly share DIY info.

Thoughts and opinions are welcomed.

And yes, I am aware that there is a law that limits maximum of 3 lights lit at the same time. And if I ever get pulled over & ticketed for this I will unplug the added wire, show it to the magistrate during hearing and off I go.

Hi,

Yes, I saw and read that thread 4 times but its for a California model.
I have a California T and the wiring is different.

 

Thanks for chiming in & sharing your thoughts.

Here's more info:

1) All the modifications I do to my car are completely reversible should the need arise.

2) There is no car inspection here in Washington State so the risk of getting a fix it ticket is extremely low.
Even if a cop issues me a ticket I can just reverse it back to stock configuration, show it to the magistrate and off I go.

3) LED consumes about 75% less power compared to incandescent bulbs. LED generates almost no heat compared to incandescent bulbs so the risk of fire is super super low.

Brake lights and rear fog lights on Cali T are LED's and since they are on an On and Off duty cycle / non constant power draw the risk of starting a fire due to overheating the wire or fuse not blowing is highly unlikely.

I also checked the tail lights fuse and it is 7.5 amp.
The same fuse powers the brake lights and fog lights so there is no added power draw to the tail lights electrical system.

I am also an electrical engineer by trade so I know a little bit about fuse rating and wire rating, & I research my projects thoroughly before proceeding to determine if the risks is worth it.

In this case - in my opinion, this is a safety issue to me and my family so I will address it & resolve it on my car.

 

With the Cali T turn signal control located on the steering wheel and the volume of the turn signal relay too low that I cant hear it - I always make sure the turn signal lights are indeed on by looking at the dashboard turn signal indicator after I push the turn signal button.

 

It may, but that would require a major redesign of the brake light system. Not worth it.

 

Hi Richard,

Thanks for chiming in.

Yes, I saw your post and hope to learn from you but as you said - a shop did it for you so you're unable to share lower level details.

I will try and figure it out.

Thanks.

Thanks,

With the nice weather here in Seattle area finally I've been spending most of time driving & enjoying my car.

Been spending time upgrading the crappy cardboard speakers & crappy aluminum tweeters (2016 Cali T with HiFi JBL Hi Power Option).
Trying to upgrade the amp too with Audison Bit 8.9 DSP Amp.
In the absence of a wiring diagram I had to check each and every stereo wire to determine which speaker is which. My HiFi option has total of 12 crappy speakers.
I had to check each wire of head unit output also.
Which wire is power, ground, etc, and this is very frustrating and time consuming.

Anyway, I put the stereo upgrade on hold so I can enjoy driving my car.

I hope to finish the brake light mod (I'm 50% done) soon and as always I will post DIY thread here once Im done for sharing with others that are interested.
