Who has used 1992 Toyota Celica master cylinder?

If you have upgraded your brakes using the 1992 Toyota Celica master cylinder, what did you do about brake lights.  The original MC has a brake pressure switch to activate the brake lights.  It does not appear the 1992 Toyota Celica master cylinder has one?  In the picutes on the Auto Parts sites it show a wire going into the cap of the resevoir but I assume that is a low brake fluid sensor?

The current light switch is built into the original MC. Not a separate piece. Are there available in line switches?

After your post I did a sewarch and do see you can purchase inline sensors.  Problem solved.  Thanks,

I'm going to use a electric switch ..... pressure switches do the job, lets be honest not the best way to do the job.

If you are just slowly moving in stop and go traffic only lightly using the brake, may not be enough pressure to activate the lights for the car following behind you.

They sometimes have other issues.

 

This switch will be easy to install, while it may work as is ... I may try to find a way to make it adjustable if it is needed.

This project is coming up soon.

Most cars/motorcycles use a simple pressure switch. It doesn't get any better.

When you use the Wilwood proportioning valve the brake light switch is built in.

I'll be using a dry switch under the dash also.   Lots of pressure switch failures in my history ,replaced several for leakage .   Especially with later replacements seeping fluid and even more especially with late 90s/early2000s Ford engine compartment fires.   Pressure switch leaked internally, shorted  and caught fire.   I lost a 2000 Expedition and an high school friend lost a similar SUV along with over $100K damage to his house.   Both fires started when the vehicles were parked and unattended, but his was in the garage.  

 

Yes they are simple and easy to install but far from being the perfect solution.
