Welcome.  Most European made mopeds from about 1970 – 2000 have high quality CEV electrical components, made in Italy. CEV is a trade mark, owned by Fratelli Pagani, that stands for Costruzioni Elettromeccaniche Venegonesi. CEV is now owned by Zadi, a maker of moped fork locks. Other European moped electrical components include switches made by Merit, tail lights, head lights and turn signals made by ULO (Germany), head lights made by Luxor (France). Some American moped electrical components are headlights, tail lights made by Peterson (USA). Asian mopeds have their own components, which are often the same as earlier Honda items. The Czech moped, Jawa, has it’s own components.

Light bulbs are very universal. Most moped light bulbs are standard automotive bulbs. Moped 4.5 inch round head lights are the same as some tractor lights, auto and motorcycle fog lights, forklift, golf cart, utility vehicle lights. Most bulbs are made in 6 volt or 12 volt versions, But finding 6V bulbs is difficult since all cars are 12V since the 1970′s.

In all of these magneto/generator powered head lights, a 12 volt bulb will replace a 6 volt one, and be almost as bright.

Bulbs are specified by their style, size, voltage, and wattage. #1,#2,#3 are bayonet style 15mm, BA15s and BA15d, where you push it in first a little, then turn it clockwise 45 degrees to go on, or counterclockwise to take off. A single filament bayonet bulb can go two ways, but a double filament only goes in one way. That’s because one prong is higher than the other on a dual filament. That’s so you can’t reverse the tail and brake lights. The BA20d hi/lo headlites are the same way. The smaller bayonets are #4, 9mm BA9S, and #6, 7mm BA7S. #5 is a festoon style bulb that looks like a glass fuse but it’s not. It’s a high beam indicator lite.

#10 and #12 are sealed beam 4 1/2″ round headlites, where the bulb is sealed inside the glass reflector and lens. Sealed beam bulbs cost much more than replaceable ones so it’s practical to upgrade to a replaceable bulb whenever possible. When your burned out sealed beam headlite is made out of metal, on the back, not glass, then Myrons Mopeds can recycle it, for $22 plus $8 parts plus shipping. Many vintage Japanese and European small motorcycles and mopeds have hard to get sealed beam bulbs, such as CEV171 or 172, with metal backs. A hole is cut and a universal bulb socket snaps in. The original wire plug(s) are re-used. The bulb is a single filament, easy to get at convenience stores, #1156. If the original had hi/lo beam, then it will have just low after the upgrade.

Above, any metal-backed (not glass) headlight can be recycled. Cut a hole and snap in a socket for an #1156 bulb.

Mopeds frequently burn out bulbs, from both vibration and surges of electricity. Because there’s no battery, the voltage varies a little. At idle the lights are very dim, but at full speed they’re bright. Hopefully they’re not bright white, as that means it might burn out soon. Yellow is good but orange is too dim. For some reason, most old 6 volt mopeds need 12 volt bulbs, or else they burn out. Some bikes need a 12V AC voltage regulator ($45) added on in addition to 12V bulbs, to help prevent bulb burn out. Only when 12V bulbs are too dim should 6V ones be used, with the following exception. The 77-later Puch needs a 6V 21W #1129 instead of a 12V 21W #1156, in order for the tail lite to be bright. Other bikes have issues where the brake light is needed for the ignition to function. Some taillights have a secret hidden resistor inside, that allows the bike to run even with a burned out or missing brake light bulb. See service section for more info about weird light behavior and what mopeds need what lights to run, if any.


L to R: 1) 4.5″ sealed beam, 6V 18W, #4667, 2) 4.5″ sealed beam, 12V 35W #4415, 3) 4.5″ head light fixture for a replaceable bulb. Click to enlarge.

The CEV 8053.1 is a handlebar mount, left side clamp-on, 3-position turn signal switch, Left-Off-Right, that came on 1970′s mopeds with CEV turn signals. It is a “round chrome” style switch that shares the same clamp with other CEV round chrome switches. For $15 you can buy the 8041 light/horn switch assy, and the 8040.3 light/horn switch base, needed to make a substitute 8053.1. Or for $25 each, you can order the substitute 8053.1 ready to install. It will have a “dummy” button that does nothing but hide the hole.

Most mopeds do not have a battery, so the electricity is all AC alternating current. Some mopeds and almost all motorcycles have a battery, usually 12 volt. Their electricity can be all DC or part DC and part AC. An incandescent light bulb works the same on AC or DC, but a horn is made for either AC or DC. DC current horns go beeeeeeeep, like a little cute car horn. AC horns sound like the buzzer when you get a wrong answer on a TV game show. AC horns also sound like duck callers. The pitch goes up with the rpm of the engine. They’re not much louder than the engine.

It is difficult to sell used or new old stock AC horns that were made 35 years ago. If they haven’t been kept in a sealed wrapper, then they might not work good, even though they’re new. It’s because corrosion can get on the aluminum plate. Furthermore, you cannot easily tell whether a horn is good or bad. You cannot easily look inside because it is riveted together. You cannot perform a valid test of it unless you have the moped it is intended to go on, running, with working horn wires and button. Because the AC an vary from one kind to another, and from a new one to an old one of the same kind, you never know if a horn that works on a Peugeot for example, would work on a Puch, until you try it. Or it might work good on Puch at low rpm, but not high. Maybe visa versa on Garelli. It also matters whether the head light is off or on. Many AC horns will not work, or are not loud, unless the headlight is off.

Myrons Mopeds has some 6V AC horns, but they are only offered when the running good moped is present in the shop and able to easily attach the horn to test it. The price is usually $20-25 for a good used AC horn.

All modern scooters and motorcycles have 12 volt DC horns. They are common. Some older Taiwanese mopeds have 6 volt DC horns. AC buzzers are “old school” and are not on anything modern. So there are no known freshly made replacements.

Far right, a CEV 2158 “bullet” headlight. It comes with a block off plate over the speedometer hole. Most European moped speedometers fit into the hole, such as CEV, VDO, Huret, Veglia. Japanese made Tatung speedos are too small. besides the beautiful classic look, hiding most of the wiring inside, the glass fixture features a replaceable bulb socket, a big benefit. With sealed beam headlights, when they (often) burn out you have to buy a whole new glass, that’s both expensive and difficult to find. But with a non-sealed beam (replaceable bulb) fixture, you can change the small 15mm bulb inside. It’s a common automotive bulb #1156 (12V 21W) or #1129 (6V21W). You can get an 1156 at all night convenience stores for $1 or $2. Another benefit is you can run an LED bulb, or any 1156 compatible. That’s a single prong bulb. No high beam, just low.

 Vintage Battery Wires: Some of the modern replacement 6 volt batteries have the wrong wires. See the image below at right, how the modern and vintage 6N2-2A and 6N4B-2A batteries have different wires. The word “vintage” used above means it has the older wires (with fuse, double female bullet, and extra wire). The vintage versions cost $10 more because the wires must be added on. Otherwise, the old battery’s wires can be transferred onto the new battery, by the customer, saving the $10.

Battery Acid: The batteries that say “without acid” are sold dry and sealed, for freshness and maximum strength. Battery acid must be added before use, but it is not included with the battery. It’s sold in auto parts stores. Walk-in customers get the battery filled at the time of sale for $5 more. 

Battery Charging: All lead acid batteries need to be kept charged, at least every 2-3 months, or they will become weaker and weaker with age. After 2 years of sitting they are less than 25% of their original strength. That’s why these batteries are sold dry. For a lead acid battery, life begins at the moment the electrolyte (dilute sulfuric acid) is added. Read the instructions with each battery. Wear eye and skin protection. Use baking soda to neutralize spills.

This is a main wiring harness for 3-or-more-coil moped magnetos (ignition, lights, brake light). It can be configured for 2-coil magnetos (ignition/brake light, lights). See below for possible configurations. It is shown as a photo and a schematic. It comes with the round chrome switches, right for engine stop, left for headlight and horn. Price is $65.


This is only the front main harness. A rear harness, engine to tail light, and connector block are needed to make a complete harness, but they’re not included.
