Using a relay isn't a particularly good idea, unless you are using an ultra fast non automotive relay, but regular automotive relays have a switching time usually around several milliseconds, which although doesn't sound a lot in an emergency situation on a motorway could mean that someone stuffs up the back of you.

It wouldn't be your fault, but I would prefer not to have to go through the hassle of going through insurance etc.

The standard switch can easily switch a pair of standard lights plus a LED high level light.

How many msec does it take for the fluid pressure to build to throw the switch? longer still when system pressure is decreased..

The pedal will always move before the brakes. I have a rapid brake light using a microswitch. Relay is needed with the discreet switch I am using. I look at switches from pendulum pedal cars, but I've not yet seen anything I prefer to what I have now.

LED eye level brake lights are a wise move on any VW :agree:

The pressure increase will be almost instantaneous ie <1ms, the time to switch with a relay will be between 7 - 10ms

I won't argue msec with no solid numbers. I will argue my brake lights are quicker than yours but not on the net..

To be honest as long as you have LED centre lights then it won't make much difference as they are much faster - I was just being argumentative

No, they are much, MUCH faster
