ULO made tail lights, reflectors, and turn signals for German mopeds, Hercules (Sachs), Kreidler, Solo, Kynast, and tail lights for many non-German mopeds, Batavus, Sparta, Puch, Peugeot, Motobecane and Honda PA50. ULO was founded by Moritz Ullman in 1947 in Geislingen Germany. Ullman knew how to make molded glass products, like bicycle reflectors. Today ULO is worldwide, making tail lights for cars like BMW and Audi.
ULO plastic parts have a date mark. The lens has the compliance standards and those have a start date.

73a 250-0016 $13 new bulb holder-mirror 1-bulb
The little rubber grommets #72 for the two-bulb holder-mirror, are important. When one is missing, the bulb holder is loose. Engine vibration causes the loose holder to “buzz” or vibrate and rub against the lens and housing. The buzzing causes the bulbs to burn out, and produces white powder. The white plastic dust or powder is evidence of “buzzing”. Slices of small rubber hose can be good substitutes.
3a. Replica ULO Tail Lights
60s $25 SIM 250 tail light, sold as is
60s $42 SIM 250w for original wires
60s $48 SIM 250m1 with ULO 1-bulb holder
60s $55 SIM 250m2 with ULO 2-bulb holder
The SIM 250w, 250m1 and 250m2 allow the original wires to be reused. The wire connectors are protected inside the light, unlike a plain SIM 250 where they are under the fender. There the tire can rub on the wires when going over bumps or with heavy a load, eventually causing damage.
61s $15 SIM 250 housing
The SIM 250 housing has no upper mount hole, so a 6mm (15/64″) hole must be drilled.
63s $$1 SIM 250 lens screw 44mm
64s $12 SIM 250 red lens
The SIM 250 lens is 2mm taller on top, and the screw hole tubes are spaced 2mm farther apart. So the lens does not fit an original ULO 250 housing.
66s $$2 SIM 250 lower bulb 12V 5W
67s 0$2 SIM 250 upper bulb 12V 10W
73s $12 SIM 250 bulb holder-mirror
The SIM 250 bulb holder-mirror is different, a metal plate with plastic bulb sockets that are loose. The bulb sockets have 3mm male blade connectors, instead of 8mm male blades like the originals. So the original wires with 8mm female blade connectors will not fit.
SIM 250m1 and 250m2 modified replica tail lights replace ULO 250-1 and 250-2 originals. They are made from a SIM 250 with the bulb holder-mirror changed to an original type.
The benefits are 1) solid bulb sockets for less bulb burn out, 2) uses the same original wires, 3) can also be one-bulb type for US-model mopeds with external ignition ground brake light wiring.
Modifications to the housing: The upper mount hole is drilled. The lens screw posts are reduced in height. The wires hole is widened enough to pass the female 8mm blade connectors through.
Modifications to the bulb holder: The top is cut down by 2 mm and the screw holes are moved 2 mm farther apart by grinding off the outer edge.
Modifications to the lens: None.
Modifications to the lens screws: The ST self-tapping screws are shortened to 50 mm.
