Modern car rear lights!

Mark Allread explained on 25/05/2017 :

No it checks every lamp.

It uses all BMW electronics, engine and gearbox.

Bob Eager was thinking very hard :

Some used an inner coloured lens, with clear outer and clear lamp.

What do you mean off topic?

Or did you really mean OTT (over the top)?

on 25/05/2017, Dave Plowman (News) supposed :

In the day, I would quieten sounders which were too loud by sticking bluetack over them and the ones which were too quiet I would make a baffle for and/or make a hole in the trim. Baffle as in tube or similar, anything which makes the air path between front and rear of the part which moves, longer.

Remember those plug in speakers for small transistor radios, where the speaker was fitted inside a cardboard tube?

It is a very handy feature, you cannot beat knowing all your lights are working and working properly. You can go round and manually check them, they can be working, but on the road one can be flickering - modern systems will detect that and warn you. The first car I had which had a basic lamp failure system was back in the 80's.

They dropped the requirement to carry spare bulbs a long time ago.

As the bulbs haven't blown, just a bit pale, I've ordered a couple of LED replacements on the slow boat from China, what E markings?

They were Irish made.

But added the requirement for a breath testing kit (alcohol not garlic)

Are you expected to test yourself each time you drive, or is it for the police to test you if they stop you?

That has also, effectively, been dropped. Although they made it a legal requirement to carry two, they did not introduce any penalty for not carrying them and have no plans to do so.

Do people know about these? Are they labelled? (I bought a couple of Bluetooth devices from Argos supplied with cables which are, in effect, charge only - but they just look like ordinary USB cables.)

It's France, so expect anything. Maybe it is to test yourself, it's just an addtional expense for no real gain.

I'd expect the police to carry their own significantly more accurate portable testers and maybe have evidential standard testing back at base like in the UK, but having only ever been roadside breath tested in Australia I wouldn't know (zero result, marginallly busted a speed limit when I missed a sign)

Northern not the Republic.

The charger may, but you use a power only cable, there cannot be any data transfer.

More likely it is using pulse-width modulation - far easier for digital and power electronics than varying the voltage.

Well, I'm not particularly 'techie', but _I_ know about them... I bought mine through Amazon - just the adapters, as I already have enough standard cables floating around.

Steve Walker explained :

Agreed and yes it does, as does the climate fan, but not the radiator cooling fan. That surprisingly uses a 100w resistor to provide half speed ;-)
