Most moped light bulbs are standard automotive bulbs. 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, but won’t be as bright.Miniature All-Glass Wedge Bulbs: 044.687 6V 1.2w 5mm wedge Osram $2.00 for Tomos speedos (CEV) late 80’s ELG74 12V 1.2w 74 5mm wedge Flüsser $3.00 for Tomos speedos (CEV black) 1990 to 2002

Sealed Beam Headlights (bulbs)Sealed beam means the entire glass lens in front and mirror reflector in back, are evacuated of air. The bulb cannot be replaced without replacing the whole glass. Moped 4.5 inch round head lights, sealed beam or non-sealed, interchange with some tractor lights, auto and motorcycle fog lights, forklift, golf cart, and utility vehicle lights. There are even clear plastic 4.5″ round 12V landscaping lights that can interchange.

Non-Sealed Headlights (fixtures for bulbs)Non-sealed headlights means the bulb is not sealed in, and can be replaced without replacing the entire glass. CEV non-sealed Headlights CEV 4.5 inch round headlights, with metal backs, interchange with other all glass 4.5 inch round kinds, also used on utility vehicles. When they burn out, a one inch hole can be cut into the center of the metal back, and a snap-on bulb socket installed. This allows the use of an ordinary, inexpensive, easy to get, #1156 bulb. This is called a “metal-backed headlight upgrade to replaceable bulb” or just “headlight upgrade”. 171 R 4.5″ glass lens/reflector, new w/04811 N/A

Generic non-sealed HeadlightsThis replaces any 4.5 inch sealed beam. Takes bulbs easy to get at USA auto stores. Single-filament only, see explanation below. Bulb socket snaps onto glass reflector. Bulb can be 6V (1129) or 12V (1156) or LED. rbh06 comes with 6V 18W bulb $30 rbh12 comes with 12V 21W bulb $30 The reason this is offered in single filament only, is because there are no common auto bulbs dual filament with around 20 watts each filament. There are 21/5 watt dual filament, but on a generator-powered moped that would quickly burn out the 5W filament, because the generator makes 20 watts. The generator watts must match the total bulb watts, or there will be an under or over-voltage. A 5 watt headlight would get super bright from an over-voltage, and soon burn out, in a few seconds or minutes. There are plenty of dual filament headlight bulbs, but they are all 50 watts and above. Because of bulb availability and watts matching, a 1960’s (6 volt #1129) or 1990’s (12 volt #1156) car turn signal bulb is the best choice for a moped headlight replacement. The #1156 is often sold in convenience stores. Headlight Clips See Headlight Section below for these clips, and headlight parts other than bulbs.
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.
Metal-Backed Sealed Beam Headlight – Upgrade to Replaceable Bulb
Any metal-backed sealed beam headlight can have a hole cut in the back. The hole allows a snap-on bulb socket to give access to the bulb. Then when the bulb burns out, the entire glass does not have to be changed. This is a big advantage.
At left is an original Honda Express headlight. At right is one that has been upgraded to replaceable bulb. When Myrons Mopeds performs this, the wires are transferred over so they still plug in the same way as before. The only minor drawback is not having high and low beam, only low. The benefit is there are many bulb choices that are inexpensive and easy to get.
