(A) Each taximeter shall be driven direct from the taxicab transmission, instead of merely connecting with the speedometer driving shaft to the taximeter head itself, using a flexible shaft and a flexible housing so connected and sealed as to be tamper-proof.
(B) Each taximeter shall be furnished with a tamper-proof switch and system of electrical distribution so that when the taximeter flag is in the earning or hired position the fare indicator on the taximeter will be lighted and the telltale light, located elsewhere on the taxicab and synchronized with the lights on the fare indicator, will be lighted. The type, design, number and location of the telltale lights shall be approved by the Taxicab Administrator. No person may operate any taxicab if the telltale lights are out of order.
(C) No person may tamper with the taximeter or any of the electrical wiring attached to the taximeter or lights on any taxicab or attach any wires, switches, pins or any other device whatsoever to the taximeter or its system or electrical distribution that could result in the improper functioning or operation of the taximeter or the light required by this section.
