Due` to the provision oi' the S-shaped bends 29
in the lamp supports the lamps ,are free to move,
within limits, in any direction within the lamp
tures 26 formed in the lamp casing, and the use
of the lamp supports as a current carrying por
tion of the electric circuit thereby dispensing

with at least one conductor to convey the current
out of the casing through the lower aperture
thereof.
to Figures 3 and 4 of the drawing wherein it will
be seen that movement of the lamps vertically or
transversely of the longitudinal axis of the casing
is permitted due to ñeidng of the bends 29; while
I claim:
ì
1. A vehicle signal device comprising a casing,
movement of the lamps parallel to the axis of the
10 casing is permitted due to the ability of the por

a pair of opposed apertures, a light source in said
twist as the relative positions of the aforemen
casing
and means engaging said light source and
tioned portions of the support are shifted. -This
15 universally resilient mounting of the lamps is par- y
ticularly useful in absorbing a great portion of thev
force of road shocks which would possibly injure
the lamps if the latter-were ‘solidly secured to
the vehicle.
