Hmm wonder if the police see them as additional headlights, fog lights or as A spot light? Note singular context "spot light or search lamp."

(a) 2 fog lamps affixed to the front of the vehicle, 1 on each side of and equidistant from the centre line of the vehicle, at equal height from the ground and so that the centres of such lamps are not less than 600 mm apart; or
(b) 1 fog lamp, if there are also affixed symmetrically to the front of the vehicle and at equal height from the ground 2 lamps of a power not exceeding 7 W each, the centres of which are not less that 1 m apart.
