No brake lights on car
Discussion
Driven wifey car all the way to seaside today and back and everytime I stopped, the car behind pulls up so close I can read the drivers vin plate on the dash!
Throw a question to wifey "does your car brake lights work?"
Get home and check - no brake lights on hitting hte brake.
Now wifey wants to take car to work tomorrow. I question what would happen if someone ran into the back of her. Normally it would be their fault, but with no brake lights, where would she stand?
(Call to Honda tomorrow and get a brake light switch to fit under the dash).

(I saw this on either Tomorrow's world or the Discovery channel). The filament temperature of a typical bulb is at least 1000C when lit, the filament will break a certain way when gets this hot.
they don't break they stretch...unless in a zillion pieces of course....

1) Bulb intact, filament ends BROKEN - probable that mechanical damage occured while lamp was UNLIT.
2) Bulb intact, filament ends MELTED - probable that mechanical damage occured while lamp was LIT, and POSSIBLE that damage occured on impact.
3) Bulb broken, filament ends BROKEN - probable that mechanical damage occured while lamp was UNLIT.
4) Bulb broken, filament ends MELTED, filament deposit on inside of bulb glass but nowhere else (outside/on lens "glass"/reflector) - probable that mechanical damage occured BEFRE impact.
5) Bulb broken, filament ends MELTED, no deposit on inside of bulb glass - probable that mechanical damage occured while lamp was LIT, and that damage occured on impact.
6) Bulb broken, filament vapourised and deposited on inside of bulb glass - probable that this occured while lamp LIT, but inconclusive regarding time of damage.
7) Bulb broken, filament vapourised but NO deposit on inside of bulb glass OR traces on inside/outside of bulb glass AND lens "glass"/reflector - probable that mechanical damage occured while lamp was LIT and that dmage occured at time of impact.
Of course there are various nuances involved here.
I got this from a member of the Forensic Science Lab at Aldermaston some years ago, so things will have moved on by now. However, it does illustrate how it can be determined with sufficient probability whether the bulb was on or off.

She would be done, Rodney, for failing to maintain a stop lamp in good working condition under Reg 23 MV Con and Use Regs 1989 which could result in the Trotter Bank Account being lighter than 1000 notes. No points.
The Plonker than runs into the back could appear at the same Court for due care.( A wise driver always maintains the "hang back" position to cope for such an eventuality).
As the lamp is a requirement under Part 1 Schedule 12 MVCUR then cannot get a pass on MOT so another offence of using wif heart. (Peckham Court full today).
Doctoring the lamps with an on/off switch causes one to start considering the offences of Dangerous Driving (knowing a fault exists by engineering and blatantly drives) and even parts and accessories in such condition as likely to cause danger. Both of which land you with points.

Of course the best solution is to junk the stone-age incandescent technology and fit LEDs. Farnell sell these really high output LEDs called "Lumileds", made by a subsidiary of Hewlett Packard. You only need one to match the light output of a filtered 21W bulb, so it's easy to modify the existing lights.
