e wires leadingfrom the small screws in the brush holders to the incandescentlight in the cab come together, a short circuit may result andthe light will go out. In that event, disconnect one of thesmall wires and look for the cause of trouble at your leisure.If the carbon holder is pushed too far ahead and comes incontact with the reflector, a short circuit will result. PRECAUTIONS TO BE OBSERVED. 19, As before urged, scrupulous cleanliness will prove thegreater factor toward securing a perfect light. Engineers shouldgive the headlight their personal attention for a few momentseach day. When engines are pooled, some competent personshould have the care of the lights. Reflectors should becleaned the same as with oil hghts. Carbons should be keptin a dry place and prevented from jarring around in boxes,causing fractures that lead to road failures. As all lightgenerates heat, the trouble experienced by the cracking of theglass in the headlight case has been met by moving this glass 5 or

Do not attempt to remove the reflectorfrom the case until the wires have been disconnected and thetop carbon holder 100 has been removed by loosening thethumb nut 79, Fig. 6. Another style of lamp is shown inFig. 7, but the foregoing directions apply equally to both styles. IXCAXDESCENT LIGHTS. 20. A small number of locomotives have been equippedwith a special incandescent circuit used to illuminate the run-ning gear, etc. Where such an arrangement is made use of, a16-candlepower incandescent lamp is placed inside of thereflector with the arc lamp. By means of a suitable switch,the arc light can be cut out and the incandescent lamps cut in,thus making it easier for opposing trains to approach, withthe additional advantage of lighting up the exterior of thelocomotive and materially assisting in case of breakdo
