    A note to old forum members...
    I receive numerous requests from people who can no longer log in because their accounts were deleted. As mentioned in the forum FAQ, user accounts are deleted if you haven't logged in for the past 6 months. If you can't log in, then create a new forum account. If you don't get an error message, then check your email account for an activation message. If you get a message stating that the email address is already in use, then your account still exists so follow the instructions in the forum FAQ for resetting your password.

    Have you forgotten your password or have a new email address? Then read the forum FAQ for details on how to reset it.

    Any email requests for "can't log in anymore" problems or "lost my password" problems will be deleted. Read the forum FAQ and follow the instructions there - that's what we have one for...

    If you are a returning visitor who never received your confirmation email, then odds are your email provider is blockinig emails from our server. The only thing that can be done to get around this is you will have to try creating another forum account using an email address from another domain.

    If you are a returning visitor to the forum and can't log in using your old forum name and password but used to be able to then chances are your account is deleted. Purges of the databases are done regularly. You will have to create a new forum account and you should be all set.

I put a pair of the "Flower" type LEDs that replace the bulbs on my GS1150 tail lights Now the stop/tail indicator in always on. Do I need to put a rsistor in series with the LED's? If so, any idea what resistence?
Thanks

No, not necessary unless they are too bright!

Resistors are usually installed in parallel over the flasher led's to help increase the load so that the OEM or load sensitive flasher unit works properly.
 
The light monitor in your panel is looking for a certain amount of current draw, indicating that the light is actually working. By changing to LEDs, you have greatly reduced the current that is flowing, and the monitor thinks the bulb has burned out. By putting a resistor in parallel, more current will flow, satisying the monitor, but you probably changed for the purpose of reducing that current, so it would be counter-productive.

Actually I changed them fro more bitghtness not current reduction. Any idea how much resistance ot put in parallel?

First of all, what lights did you get, and, ... did you get the extra brightness you were looking for? :-k

Too many times, the LED replacement 'bulbs' only have a small 'bright' spot and don't fill the entire area.
Let us know what you got and how you like it. Pictures would be nice, too.

The stock tail light is about 2 or 3 watts, meaning about 1/4 amp. To get that, you would need about 50 ohms.
