Does anyone know where I can get one for a 2016 IS350 F Sport?

 

If you are referring to the rear deflectors that you have to wire up to your brake lights, ijdmtoy sells them for $70

Didn’t know you could replace the deflectors on the valance with ones that lit up. Very cool.
No I mean a diffuser to replace the valance and which has a break light in the middle of it, like this


I know Nia Auto Design has an attachment but it only fits the 2017 valance.

 

Lexon had a rear diffuser with a 3rd brake light option. I'm not sure who is the best supplier to get this from though.

 

LEXON Rear Diffuser for Lexus IS 2014-20


ROWEN Rear Half Diffuser for Lexus IS 2013-20

 

You can swap out the 2016 rear diffuser for a 2017+ version and look into the Nia Auto diffuser add-on with a brake light.

What is the purpose of the 4th brake light? Just curious...

 

Mostly a cosmetic thing... but it can be an added safety feature as well I guess. Kinda like replacing the lower rear reflectors with lights.

 

I was just going to ask this and see if it was interchangeable. This might be the cheaper route considering I’m in Canada.

Yes the brake light is more for cosmetics.

 

I found this site. Not sure the quality of their products but they happen to sell 2 diffusers with break lights.

Subi guys would argue for safety and in some situations, it could be invaluable...i.e. thick fog, pouring rain, snow, etc.

What I always remember is cars with a 3rd brake light vs. Just tails were far less likely to get in accidents in comparison to 2 brake lights, thus almost all cars have a 3rd brake light now


One could argue, a 4th brake light could help in even more in avoiding rear end collisions
