Guidelines for fitment of end
outline marker lamp, side marker
lamp, side retro-reflector, side
indicator, front fog lamps and
rear fog lamp, head lamps, tail
lamp assembly and side retro-
reflector during body building
(refer figure)
For factory built load body all the
above fitments come as OE, except
fog lamps.
Front and rear fog lamps are optional
and only provision is given.
1. End outline marker lamps: A, B,
C, D, E and F in the sketch are typical
six locations of End outline marker
lamps. Normally four lamps are fitted,
two for the front (white light) and
two for the rear ( red light ). The rear
lamps can be fitted at locations
suitably to be visible from the rear
of the vehicle. Visibility for both front
and rear lamps is defined as
horizontal spread about the lamp axis
of m/- 80 deg and the
vertical spread of minimum 5 deg
above and minimum 21 deg below
the axis of the lamp. They are
normally mounted near the top of
the vehicle; the height should be
such that it is minimum 200 mm
above the parking lamp. From the
sides of the vehicle, the lamps
should be fitted at a distance less
than 400 mm. Refer figure. The
wattage of the lamps should be 5
watts.
2. Side ( turn ) indicator lamps : G
and H are the typical locations of
side indicator (turn indicator) lamps.
The height restrictions of the lamp
are given in the figure. The wattage
of the lamp should be normally 10
watts.
3. Side marker lamps & Side
retro-reflectors: I,J,K,L,M and N are
the typical locations of side marker
lamps and side retro reflectors. These
are to be fitted on all vehicles of
overall length more than 6 meters.
The distance restrictions are given in
the figure. The side marker lamp
and side retro reflector may be
separately fitted or can both be
included in a single package. The
wattage of side marker lamp should
be 5 watts. The distance restrictions
are given in the figure. Refer figure
for circuit diagram.
4. Front fog lamps: P and Q are the
typical locations of the front fog
lamps. The distance restriction from
the sides of the vehicle and the
height are given in the figure for
Front and Rear fog lamps. The
wattage of the lamps should be 55
watts each. Refer figure for circuit
diagram.
5. Rear fog lamp: R is a typical
location of the rear fog lamp. The
distance restrictions from the
longitudinal centre line of the
vehicle and from the side of the
vehicle are given in the figure for
Front and Rear fog lamps. The rear
fog lamp is to be fitted on the
driver’s side of the vehicle typically
as shown in the figure. The wattage
of the lamp should be 21 watts. Refer
circuit schematic.
6. Head lamps: The head lamps are
supplied along with the vehicles
from the factory. The distance
restrictions for mounting of the
lamps during body building are given
in the figure .
7. Tail lamps: The tail lamp
assemblies are fitted as part of
factory supplies on our vehicles. The
assembly consists of rear position
lamp, stop lamp, rear retro-reflector,
reversing lamp and turn indicator.
The distance restrictions for
mounting the lamp assembly are
given in the figure .
