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.

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.

Bulbs 2bCEVCEV 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”.

These are new GE 4667-1 sealed beam headlight bulbs, that have been converted (upgraded) into non-sealed fixtures by cutting a one inch hole in the back. The back is glass, so cutting it, without cracking, is done underwater with a high speed diamond burr.

 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


Honda Express headlight upgrade

Honda Express headlight upgrade

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.
