I'm thinking of fitting (or having fitted) a couple of spotlights on the D2 so any thoughts on make would be very welcome: also would you have them slaved to the on-board fogs, separately switched, or the headlights main beam?

when i’ve fitted spots , wired them into the main beam loom, then fitted a separate switch so can have the spots come on or off with the main beam

was lazy and bought plug and play looms but know many on here have made there own looms up

If you intend using them on the road they HAVE to come on with main beam only.
 
Why would you wish 'not' to have them on along with the main 'high' beam ?
People with extra lights on the front of their vehicles often have strange ideas regarding which ones to use and when.
I'm installing wiring for extra lights as part of my loom build but won't be fitting lights until I feel they're necessary. Relay will be triggered by high beam circuit so will automatically go off when dropped to normal/low/dipped or whatever it's known as.

On a 30A relay, triggered off the full beam, it's like daylight out there when I hit the full beams :)

Why would you think to trigger off your front fogs? Bit random :confused:

Either separate switching or triggering off your full beams. be sure to relay them in with fuses and please don't take this personally but do not skotchlock into the trigger wire, sheath it and solder or you can use any number of connectors to make a good electrical contact that can be sealed from the elements.
 
Or if you do motorway driving in warmer countries too fit them on the roof or where ever you want but not in front of the radiator cos it will affect bad the cooling, intercooling and the climate control... they restrict from 25 to 50% the air flow through the radiators depends on how big they are and how they are fitted ... that's a fact based on live measurements made by me on a friend's vehicle with and without spots on motorway, the ECT and IAT were both higher with up to 10*C, ECT above 100 all the time and due to the higher IAT the EGT was a bit higher too. Each for his own but i would not fit spots un front of the grill whatsoever

this is a good ideea :cool::

Wow - is that legal?

That's quite an array of lights - should be able to find my way with that lot. But remind me please, was there not a law many years ago that any spots fitted to a vehicle had to be not more than so many inches above the ground and a certain minimum width apart? I take it that has all gone.

Spots are classed as auxillary lights for the purposes of the regs.

No height or width restriction only matched pairs (or symmetrical around the centre for bars) and switched to main beam.

It's a recurring topic and if you want to see the regs a search will bring them up :)

Pah! :p:p:p

It is perfect at what it does, there are another 6 7" light bars for the roof bar, but alas I don't have enough amps off the alternator for them all to be fitted at the moment.

I like - not sure I've got the nuts to drive it though, but lights, wheels, colour - smart
 
@Frenchdame - Having them switched off your fog lights wastes the purpose of the fogs.
Driving in actual fog, not a pathetic mist, fog lights allow you to illuminate and be seen, but don't bounce the light back into your face like headlights do, because they're nice and low. It's a shame the majority of drivers don't understand this.

Cheers - I understand but wasn't sure of the legals. Having seen such an array of spots I wondered if they were switched solo for off-road or for general use. I rarely use the spots on the D2 except to be seen. Some years ago, in the early hours of the morning I was slow cruising home after covering the Kings Cross tube fire: a rainy, dirty night and I put my spots on with low beam - and was pulled in by the Met's finest and told it was illegal for me to use them unless it was foggy. I started to argue - three a.m. (wrong of me) wherein they breathalysed me - negative - an then gave me another bollocking. Often wondered why cops don't like us using common sense!
