That's the dim-dip thingy that makes people think that just because the light comes out of the headlight aperture it's good enough to drive on in the fog - sorry, favourite gripe!
You should have conventional sidelights only with the engine stopped. The dim-dip thingy comes into effect when the engine is running (actually 'ignition' on, I think).
From the RVLighting Regs.
" The electrical connections to the obligatory dim-dip device or running lamps, as the case may be, shall be such that the light output specified in paragraph 1 or 2 above is emitted automatically whenever-
(a) the engine of the vehicle is running, or the key or devices which control the starting or stopping of the engine are in the normal position for driving the vehicle, and
(i) the obligatory position lamps, but not the headlamps, of the vehicle are switched on, or (ii) the obligatory position lamps are switched off."
Sure it's not just a PO mod - new headlight units with integral pilot lights, wired to come on with the sidelights? I did that to my 90 when I upgraded to halogen lights. If so, they'll only be little 5v things.
Too right matey, nowt damaging, but i'll give it the beans....
Not sure about the site, Jane does all that kind of crap...
The last one was 130 miles away & i had the worst ear infection i could imagine, i felt like death for 3 weeks I can tell you. The only upshot was I actually got to use my machete!
But the advantage of Dim Dip in normal conditions, i.e. non-foggy, is that it prevents cretins from driving on only parking lights. Not such a problem in something like an RRC with dedicated side light units, or the older Volvos with 25W day running units, but astoundingly dangerous in vehicles where the
