Are my brake lights supposed to look like this?

I was driving behind my model 3 today, (hey, gotta give the wife a turn every so often!) and saw that my brake lights are just these little red strips. Is this normal? I thought the outer-C/reverse-C might also illuminate when braking during daylight hours??

I really think after seeing several in day and night that aftermarket taillights with more lighted area in them could be a good seller
Maybe a neater design and just plain brighter , I fear being hit from behind
The Leaf had those huge vertical tail lights , always felt visible. Ugly , but visible

Personally I think Audi has the best looking taillights going and have had for years. I do like the 3’s as well including brake and turns.

Has anyone considered adding an additional light? I’ve seen online several third brake light turn signal combos like the one pictured? I’ve not seen any aftermarket tail lights available so this was the only options I could find.

I have always put a brake modulator or brake wig-wag on my motorcycles; with the Model 3 having brake lights that are mixed with the turn signals (bad decision, Telsla!) I've been considering putting a modulator on the CHMSL (third brake light).

Has anyone figured out
- how to get up into that area, or
- where the wiring harness for that runs, or
- what the connectors are (for a splice-free and reversible install)?

You can do it all without tools. You have to start by folding down the rear seats, remove all the side trim and the C-Pillar covers, then you can remove the push-tree fasteners from the rear deck cover, release the 2 side latches, then it pulls forward and up.

The CHMSL (center brake light) is controlled by VCRIGHT which is the Body Control ECU located in the passenger side (right) kick panel. So that would be an easier place to intercept the wire without taking the back of the car apart as outlined above.

It's a .35mm2 blue wire going into pin 20 of 52-pin connector X050. It's the largest connector on the ECU and the it's part number is a Sumitomo 6098-8363, so you might be able to find a diagram online. If you wanted to do it w/o cutting wires, the easiest way would be to remove the terminal from the connector body and then insert a new one. The terminal used is Sumitomo #8100-3625.

(Yay! @Ingineer is back!)

Thanks! Best ground on X050?

BTW, did you see that one guy who received a 3 with one US taillight assembly and one EU, and the EU worked as expected? I can’t find the post again, but I saw it... somewhere.
