Legal stuff re "Driving" lamps

<< < (3/8) > >>

Moose:
I know what little street cred in the off road world will now completely disappear, however I have fitted Corsa boy blue ( what other colour ?) LED washer jets. :oops:

Back to the lorries, ok so they are linked to dip beam, but surely they cannot be legal if used, particualy the roof mounted ones. If so, why fit them?

Arhhhhhhh............... no  :shock:

I can't really as my washer jets are not on the bonnet so no point really :roll:  

Got to ask though, how are they powered :?:

I can't as I don't have any washer jets :)


As for the lorries they probably have a switch that allows them to have main beam with or without the spots, which'll get around the VI checks. Still AFAIK not legal to actually use on the road but the c&u rules could be different for commercials.

BTT... a bit of 'further reading'
Statutory Instrument 1989 No. 1796 The Road Vehicles Lighting Regulations 1989

Front fog lights - maximum distance in from side of vehicle - 400mm, maximum height above ground - 1200mm

Main Beam Headlamps (presumaby spotlights or driving lamps) no horizontal or vertical requirements other than horizontally the outer edge of illuminance must fall inside the outer edges of normal dipped beam illuminance (the area that is lit up Dyf!  :P )
No requirement on minimum or maximum wattage (except for motorcycles)
Electrical Connection - every main-beam headlamp shall be so constructed that the light emitted therefrom-
(i)  can be deflected at the will of the driver to become a dipped beam, or
(ii)  can be extinguished by the operation of a device which at the same time either-
(A)  causes the lamp to emit a dipped beam, or
(B)  causes another lamp to emit a dipped beam

So... I read that to be I can have spotlights anywhere I want as long as they only come on with main beam?
I do have fog lights as the inner set on the roof rack, with spotlights as the outer set.
All my spotlights are wired via two way and off switches such that I can select whether they come on with main beam, isolated out of circuit altogether or are switched on independent of everything else.
Normal road driving I have the roof lights switched to off unless its one of those annoying little euro boxes that pull out on me on the motorway!  :evil:

George the Disco:
Sounds reasonable to me. I think that the trucks with loads of extra lights get away with having them as they have such a farty little voltage going through them that they are rated as being "optional vehicle identifying" lamps or something like that.

BTW, how do you wire a lamp up so that it has such a slight brightness  and then come on full power with the main beam? A double filament bulb?
