Lamp Troubleshooting and Other Information

Premature burnout - if a lamp fails immediately after it is installed, check for the correct voltage at the fixture. A 30 volt lamp that is installed in a 75 volt fixture will burn out immediately in full bright position of the headlight dimmer switch.

Weak lamp output - if a lamp appears to have a weak light output, check the rated lamp voltage. A 75 volt lamp installed in a 30 volt fixture will have a weak output. Lamp beam flicker - if the lamp beam is vibrating while traveling down the track check that the sealing ring is tightly clamping the lamp into the fixture.

Tripping headlight circuit breaker - this could be a short circuit in the headlight circuit, but typically it is an incorrect set up of a trailing locomotive. The multiple unit (MU) headlight control switch must be set up correctly on each trailing locomotive. This will permit remote operation of the headlight on the last locomotive in the consist as controlled by the leading locomotive. If the MU headlight switch is correctly set on the last unit, but the headlight switch on the control stand/console is ON this will cause the headlight circuit breaker on the lead unit to trip. Ensure the headlight switch on all trailing units is OFF. There have been cases of inferior offshore made lamps having a short circuit and tripping the headlight circuit breaker. It is best to use superior quality made in USA Amglo Kemlite lamps. Don't take chances on proper illumination - use the best long life Amglo Kemlite lamps for a safer operation.

Standardization of lamps - many railroads have converted 30 volt locomotive headlights to 75 volt lamps to standardize stocking of 75 volt lamps. This will also eliminate the confusion of using the correct voltage lamp in the lamp fixture. This also saves on ordering and stocking of two different PAR56 lamps.

Save energy by using 75 volt headlamps instead of 30 volt headlights. The dimming resistors mentioned above consume and waste power when lowering the voltage from 75 to 30 volts. Less power consumed means less fuel or electricity consumed which will save your railroad money. The elimination of dimming resistors also simplifies circuitry and reduces replacement of these resistors when they fail. A simpler circuit is always a more reliable circuit.

The long life of Amglo Kemlite PAR56 lamps means that the lamp fixtures are not opened very often. This can cause the fixture fastener to be difficult to use. The thumbwheel nut or wing nut that keeps the fixture closed should be lubricated periodically to enable easy use. Also lubricate the hinge on the fixture. Flashing ditch lights - some rail operators use a ditch lamp controller to flash the ditch lights when the horn is operated. We performed an extensive laboratory test and found that there is no degradation of performance of Amglo halogen lamps when flashed.
