So, the rear lights

I'll throw another one in: I have, on occasion, left the car in drive, but applied the parking brake rather than leaving my foot on the brake pedal.

I should have worded my question differently: Am I breaking any rule here?

Again, I have no idea. The Highway Code isn't my preferred bedtime reading, I just knew where to look reagrding lights that (MUST NOT, according to the HC) dazzle anyone.

hmmm... not sure. Is it any different to having your foot on the brake pedal?

In the context of this topic, there's a whole world of difference because leaving the car in drive and applying the parking brake rather than keeping your foot on the brake pedal will not show high intensity lights to the rear and so will not dazzle anyone behind.
