Retaining spring for H1 bulbs

[Craig.K.Yandow at aero.org]

I have 93-95 Hella S2 Version H1/H1 Elipsoid headlights.   One of the bulb
retaining springs for the low beam bulb is broken.   Right now, the light
is working, because of a coil spring and paper clip kluge.
May not last forever and the others may fail on a dark night like the first
one did.   Of course there were cold, clumsy fingers involved.
Anyway,  BLAUfergnügen, who sold me the lights can not get replacement
parts. . .
Anyone know where I can get those little hold in clips?
TIA
Craig
