Tail lights: 1970’s and 1980’s USA moped models generally have different tail lights than European models. That is because of the 1972 and 1976 US DOT motor vehicle safety requirements for motor-driven cycles and motorized bicycles. The rear light must shine to the rear and the sides, and illuminate the license plate. The rear of the bike must have red side and rear reflectors. Putting the reflectors with the tail light eliminates the need for adding them on elsewhere. Also the bulbs are bigger, 15 not 9mm, because of higher watts required for the running light, 5 watts instead of 3, and for the brake light 10 watts instead of nothing.
The most troublesome US DOT requirement was that the brake light operation cannot cause the head light to get dimmer. This meant that the brake light had to be powered by a separate source coil in the magneto-generator. There was no solid-state voltage regulation until the mid-1980’s. The AC voltage was crudely regulated by generator magnetism, rather than a external mechanical or electronic device.
Internal ignition ground family: Some US moped versions had an additional source coil to operate the brake light, such as Puch or Batavus (Bosch magnetos). On these the brake light wires never cause the engine to not run. The ignition source coil is grounded internally, inside the generator. So the ignition is never affected by any of the lights.
The brake light only needs to be matched with the generator source coil, usually 6 volt 10 watt. Unlike your house, a higher wattage bulb makes less light. If a 6V 18W bulb is used, it will be dim. If a 6V 5W bulb is used, it will be too bright and burn out.
External ignition ground family: Some US mopeds use the ignition source coil to operate the brake light, such as Garelli or Minarelli with (CEV magnetos). On these the brake light wires can cause the engine to loose spark and not run. If the connecters or wires are corroded or loose, on the brake light wires, the engine will stall when the brakes are applied. If the brake switch wires up at the handlebars are also loose, then the engine will not ever “have spark”. Removing the tail light assembly, or changing it, can cause these bikes to not run.
The brake light needs a 4 ohm (10 watt max) resistor in parallel with a 6 volt 10 watt bulb #81, or just a 6 volt 18 watt bulb #1129, or a 6V 21/5W #1154 dual filament bulb. For a brighter brake light but a weaker ignition spark, the resistor can be 6.8 ohm 10 watt.
Modern family: After the 1980’s, thankfully, there were no more mopeds with external ignition grounds. They had internal ignition grounds. So the brake light wires never cause the engine to loose spark. Their solid state AC voltage regulators allowed all the lights to run off of the same generator wire, yet still stay the same brightness as additional lights (brake) were turned off or on. The modern family also uses 12 volt bulbs instead of 6 volt.
The brake light bulb does not need to be any particular wattage. Just like in your house, a higher wattage bulb would produce more light. You want the brake light to be brighter than the tail light, for safety, but it doesn’t need to be.
Price List: Prices are for each item. Bright green means new. Dark green means used. N/A means not available.
Screws: M means metric machine screw M3, M4, M5, M6. ST means self tapping screw (for plastic).
2. CEV Tail Lights
Many or most 1970’s European made mopeds, USA models, use CEV tail lights, made in Italy.
CEV 9350: Many 1972 -1976 US mopeds had this “oval with flat sides” single bulb lamp. It was exclusively on mopeds with an external ignition ground. If the brake light burned out, the bike would loose spark when the brakes were applied. Internal ignition ground bikes did not use this lamp because it made the brake light too dim (because the 10 watt generator coil did not match the 20 watt bulb filament).
CEV 9400: In 1977 the 9400 “rectangular” series dual-bulb lamps came out, with two different bulb holders and three body styles. They could be for either family, internal or external, because the bulb holder could be either a “large glass” 18 or 21 watt brake light bulb, for external ignition ground types, or a “small glass” 10 watt brake light bulb version, for internal ignition ground types. At first the 9400,9401,9417 and 9400.1,9401.1,9417.1 were the versions. These were perfect for motorcycles with batteries.
To solve the problem of loosing spark if the brake light burned out, CEV made versions special for USA mopeds, with a power resistor hidden inside. If the brake light burned out, the resistor would allow the engine to stay running. The 9400.2, 9401.2 and 9417.2 soon superseded the 9400.1, 9401.1, and 9417.1. So the “1” versions are uncommon in the US, and the “2” versions are uncommon in Europe.
Of these, the 9400 and 9400.2 are common.
The 9400.2 is on 1978-89 Derbi.
The 9400 is on 1980-83 Piaggio Grande
Of these, only the 9401.2 is common.
It is on 77-78 Garelli and others.
Of these, 9417 and 9417.2 are common.
The 9417.2 is on 1977-85 Tomos, and 1979-85 Garelli.
The 9417 is on 1987-2011 Tomos, and 1978-86 Puch.

2a. Replica CEV Tail Lights
These lamps look exactly like the original CEV 9417 on the outside. But inside the bulb holder-mirror is different. It is a single bulb type that cannot be swapped for an original 2-bulb type. In the USA, in motorcycle parts stores, the single dual filament bulb has limited choices in volts and watts. There is just 12V 21/5W #1157 or 6V 21/5W #1154.
Because of the bulb availability, this lamp with a 6V 21/5W #1154 bulb is a good substitute for 9417.1 or 9417.2, without any resistor. But it is not a good substitute for 9417 because 6V 10/5W or 12V 10/5W dual filament bulbs are unavailable in USA auto parts stores.
The three male blade connecters have a tiny barb on top. The barb can be depressed with a tiny screwdriver. That allows the connectors to be removed. Then the original lens and/or bulb holder can be transferred onto it. But modification is required. More to follow…
This lamp also looks exactly like the original CEV 9417. Inside it has a 2 bulb holder-mirror. The bulbs can be 6 or 12 volt, and 5 or 10 watt. A 1970’s bike needs 6V, but a 1990’s or later needs 12 volt bulbs.
This entire lamp is a good substitute for CEV 9417.
Many 1970’s US-model bikes had a “secret” ignition ground resistor hidden inside this light. It allowed the bike to run even when the brake light was missing or burned out. This new light cannot hold a resistor, but one can be added to the ignition ground wire above the engine. The resistor costs $5 or $6, listed above.
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.
ULO plastic parts have a date mark. The lens has the compliance standards and those have a start date.

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”.
3a. Replica ULO Tail Lights
ULO 250 replica $30 sold new “as is”, no upper mount bolt hole, loose bulb sockets
ULO 250 replica $30 12V 10W upper bulb, 12v 5W lower bulb, wires with no connectors
These look the same on the outside. But the bulb holder is different, a metal plate with plastic bulb sockets that are loose. You can see in the middle photo that the inside wire connectors are bare metal and almost touch the metal bulb holder, which is grounded. The light would flicker off and on if they did touch. No rubber cushions/grommets and loose shaking bulb sockets will make the bulbs burn out frequently from vibration. Besides that there is no upper mount hole or mount screw, but a hole can be drilled.
Despite the things that are wrong with this light, it is still useful. The lens is made well and replaces ULO. The black housing can be modified to fit ULO, by drilling a 6mm center mount bolt hole, and grinding down the lens screw posts by 2mm.

The fender mount was made to interchange with CEV 9417. The upper 6mm stud on CEV 9417 was very short. That made the special shoulder nut necessary, on 1978-2012 Tomos with CEV 9417. This Saturnus mount uses separate bolts, which are longer. That eliminates the need for a more costly shoulder nut. So Saturnus mount uses a 2mm shorter nut, 2mm longer bolt, 2mm longer spacer. This makes the bolts/nuts 2mm closer to the rear tire.
Fiem tail and turn lights are made in India. On US models, Fiem rear lamps are on early 2000’s Hero Pacer, Panther, Ankur (Hero Majestic), Cosmo Stinger (Mont) and Avanti Autopower, Mont, Supersport, Kobra (Mont) mopeds.
These two lights are the same. The Avanti one is missing the lower red reflector and left side reflector. The Hero one is missing the right side reflector. The top bulb is bigger for the brake light, 12V 10W with base BA15S (bayonet 12 mm single contact). The bottom bulb is smaller for the tail light, 12V 4W with base BA9S (bayonet 9 mm single contact). The tail light also illuminates the license plate through a clear bottom in the red lens.
The Avanti wire colors are yellow = tail, green = brake, black = ground. See wirings for more.
