Sec. 229.125  Headlights and auxiliary lights.

    (a) Each lead locomotive used in road service shall have a headlight 
that produces a peak intensity of at least 200,000 candela. If a 
locomotive or locomotive consist in road service is regularly required 
to run backward for any portion of its trip other than to pick up a 
detached portion of its train or to make terminal movements, it shall 
also have on its rear a headlight that produces at least 200,000 
candela. Each headlight shall be arranged to illuminate a person at 
least 800 feet ahead and in front of the headlight. For purposes of this 
section, a headlight shall be comprised of either one or two lamps.
    (1) If a locomotive is equipped with a single-lamp headlight, the 
single lamp shall produce a peak intensity of at least 200,000 candela. 
The following lamps meet the standard set forth in this paragraph 
(a)(1): a single operative PAR-56, 200-watt, 30-volt lamp; or an 
operative lamp of equivalent design and intensity.
    (2) If a locomotive is equipped with a dual-lamp headlight, a peak 
intensity of at least 200,000 candela shall be produced by the headlight 
based either on a single lamp capable of individually producing the 
required peak intensity or on the candela produced by the headlight with 
both lamps illuminated. If both lamps are needed to produce the required 
peak intensity, then both lamps in the headlight shall be operational. 
The following lamps meet the standard set forth in this paragraph 
(a)(2): a single operative PAR-56, 200-watt, 30-volt lamp; two operative 
PAR-56, 350-watt, 75-volt lamps; or operative lamp(s) of equivalent 
design and intensity.
    (b) Each locomotive or locomotive consist used in yard service shall 
have two headlights, one located on the front of the locomotive or 
locomotive consist and one on its rear. Each headlight shall produce at 
least 60,000 candela and shall be arranged to illuminate a person at 
least 300 feet ahead and in front of the headlight.
    (c) Headlights shall be provided with a device to dim the light.
    (d) Effective December 31, 1997, each lead locomotive operated at a 
speed

[[Page 406]]

greater than 20 miles per hour over one or more public highway-rail 
crossings shall be equipped with operative auxiliary lights, in addition 
to the headlight required by paragraph (a) or (b) of this section. A 
locomotive equipped on March 6, 1996 with auxiliary lights in 
conformance with Sec. 229.133 shall be deemed to conform to this 
section until March 6, 2000. All locomotives in compliance with Sec. 
229.133(c) shall be deemed to conform to this section. Auxiliary lights 
shall be composed as follows:
    (1) Two white auxiliary lights shall be placed at the front of the 
locomotive to form a triangle with the headlight.
    (i) The auxiliary lights shall be at least 36 inches above the top 
of the rail, except on MU locomotives and control cab locomotives where 
such placement would compromise the integrity of the car body or be 
otherwise impractical. Auxiliary lights on such MU locomotives and 
control cab locomotives shall be at least 24 inches above the top of the 
rail.
    (ii) The auxiliary lights shall be spaced at least 36 inches apart 
if the vertical distance from the headlight to the horizontal axis of 
the auxiliary lights is 60 inches or more.
    (iii) The auxiliary lights shall be spaced at least 60 inches apart 
if the vertical distance from the headlight to the horizontal axis of 
the auxiliary lights is less than 60 inches.
    (2) Each auxiliary light shall produce a peak intensity of at least 
200,000 candela or shall produce at least 3,000 candela at an angle of 
7.5 degrees and at least 400 candela at an angle of 20 degrees from the 
centerline of the locomotive when the light is aimed parallel to the 
tracks. Any of the following lamps meet the standard set forth in this 
paragraph (d)(2): an operative PAR-56, 200-watt, 30-volt lamp; an 
operative PAR-56, 350-watt, 75-volt lamp; or an operative lamp of 
equivalent design and intensity.
    (3) The auxiliary lights shall be focused horizontally within 15 
degrees of the longitudinal centerline of the locomotive.
    (e) Auxiliary lights required by paragraph (d) of this section may 
be arranged
    (1) to burn steadily or
    (2) flash on approach to a crossing.
    If the auxiliary lights are arranged to flash;
    (i) they shall flash alternately at a rate of at least 40 flashes 
per minute and at most 180 flashes per minute,
    (ii) the railroad's operating rules shall set a standard procedure 
for use of flashing lights at public highway-rail grade crossings, and
    (iii) the flashing feature may be activated automatically, but shall 
be capable of manual activation and deactivation by the locomotive 
engineer.
    (f) Auxiliary lights required by paragraph (d) of this section shall 
be continuously illuminated immediately prior to and during movement of 
the locomotive, except as provided by railroad operating rules, 
timetable or special instructions, unless such exception is disapproved 
by FRA. A railroad may except use of auxiliary lights at a specific 
public highway-rail grade crossing by designating that exception in the 
railroad's operating rules, timetable, or a special order. Any exception 
from use of auxiliary lights at a specific public grade crossing can be 
disapproved for a stated cause by FRA's Associate Administrator for 
Safety or any one of FRA's Regional Administrators, after investigation 
by FRA and opportunity for response from the railroad.
    (g) Movement of locomotives with defective auxiliary lights.
    (1) A lead locomotive with only one failed auxiliary light must be 
repaired or switched to a trailing position before departure from the 
place where an initial terminal inspection is required for that train.
    (2) A locomotive with only one auxiliary light that has failed after 
departure from an initial terminal, must be repaired not later than the 
next calendar inspection required by Sec. 229.21.
    (3) A lead locomotive with two failed auxiliary lights may only 
proceed to the next place where repairs can be made. This movement must 
be consistent with Sec. 229.9.
    (h) Any locomotive subject to Part 229, that was built before 
December 31, 1948, and that is not used regularly in

[[Page 407]]

commuter or intercity passenger service, shall be considered historic 
equipment and excepted from the requirements of paragraphs (d) through 
(h) of this section.
