Can someone please describe the difference between Driving Lamps, Fog Lamps and Spot Lamps.

I'm looking for a pair to get for my Mini for a road rally coming up soon...which would be best for that?

Thanks, Chris

Fog lights are an intense wide low pattern for cutting under the fog, hence low.

Spot lamps are long range lamps with a long narrow pattern for high speed driving (in a straight line)

Driving lamps are a cross, ie medium to long range and a little wider than the pattern created by spot lamps

Hope this helps

Ah right, cool. Thanks very much

For a road-rally car, which is only allowed 2 extra lights, the best lights are the PIAA driving lights, although they are expensive. A good alternative is the Cibie Super-Oscar driving light. That's what I run on my 1964 Cooper 'S'.
Both will take 100 w bulbs, but you do need to have a good relay when wiring them in. Don't forget that the regulations require that they go out automatically when you dip the main beam, so the relay 'signal' feed must come from the main-beam circuit to a switch to the relay.
I hope this helps.
Spot or long-range lights are too much of a pencil-beam for rallying and fogs don't have any range, so always stick with driving lights.
