Discussion Overview

The discussion revolves around finding specific taillight and brake light bulbs for a 1978 Puchs moped, focusing on the required specifications of 6V and 12V bulbs with particular wattages. Participants explore the challenges of sourcing these bulbs in Milwaukee and clarify the meaning of "candle power" (CP) in relation to bulb brightness.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant, Shawn, expresses difficulty in finding 6V and 12V taillight/brake light bulbs in Milwaukee and questions the meaning of CP.
  • Another participant suggests that taillights are usually 2057 bulbs and questions the relevance of the 6V specification.
  • Shawn clarifies that the bulbs are for a 1978 Puchs moped, which requires 6V bulbs.
  • A participant provides various links to websites that may have the needed bulbs, indicating that some sources might be more promising than others.
  • One participant explains that CP refers to candle power and discusses the relationship between voltage and power output, suggesting that the brightness of the bulbs can vary significantly based on these factors.

Areas of Agreement / Disagreement

Participants do not reach a consensus on the best source for the bulbs, and there is uncertainty regarding the specifications and relevance of CP in this context. Multiple viewpoints on the bulb types and their applications are presented.

Contextual Notes

There are limitations regarding the assumptions about the relationship between CP and wattage, as well as the specific requirements for the moped's lighting system. The discussion does not resolve the exact specifications needed for the bulbs.

so i am trying to find taillight/ brake light bulbs
i need a 6v 10 w (12 v 20 w)
and a 6 v 5 w (12 v 10 w)
and autostores are worthless in milwaukee
none of the carriers have the Wattage listed
they have the CP
i amnot sure what the CP is on these bulbs?
is there a direct relationship to figure it out?
thanks

I'm not sure why you would spec a car light bulb at 6V, but here's a helpful website with car light bulb info. Taillights are usually 2057. Does your old bulb have the number 2057 anywhere on it?

sorry its not for a car but for a 1978 Puchs moped
hence only the 6 volts

Yikes! Okay, back to google:

website with older scooter bulbs for sale:
http://www.dynamo.mz-b.de/lights/lampen.htm

discussion forum mention of scooter bulbs:

MopedWarehouse.com and MopedGuru.com (Tech Support questions):

light bulbs at MopedWarehouse.com:

That last link looks the most promising. Good luck! -Mike-

CP = candle power, one filament is going to produce more than twice as bright a light when the brake light is applied compared to the running light.

And if you double the voltage, you get 4x the power, minus the increased resistance from increased temperature of the filament, so its ends up at pretty much 3x the power for double the voltage. So make sure you account for this if the CP is given for 12V instead of 6V CP.

For what you looking for, a close match would be 2-3 CP and then 5-6 CP for the two filaments a 6V (or 9CP/18CP at 12V), this is based on a guess of roughly 6Lumen/W and 12Lumen=1CP which should be close enough for this application.
