    How to slow down LED turn signals on MP3 500

    I have a 2009 MP3 500 and switched to LED turn signals. They blink really fast while the emergency flashers remain "normal" speed. Are there any relays or anything that can slow down the blinkers? thanks

    When you use LED bulbs in turn signals you need to replace the flasher relay with one that uses a timer instead of a bi-metal strip that heats up to make them flash. Usually the problem will be that the signals won't flash at all since the LED bulbs don't draw enough current to heat up the bi-metal strip.

    Double check that the LED bulbs do not already have a resistor in them as it may be emulating too high a wattage bulb or that you do not now have a short circuit somewhere.

    Adding resistance to LED bulbs to make them work in turn signals defeats the purpose to me since you are now creating extra electrical loads with the resistor to match what the incandescent bulbs were using to in effect trick the flasher into working properly so in the end you are still drawing the same amount of current as before and potentially more.

    BTW: What was the goal that you were seeking from the LED conversion? Power savings, longer bulb life or just for the sake of it?

    Thanks for the responses. When I purchased the bike, it had been dropped on it's right side and the front turn signal was broke. The dealer gave me two sets of led's to change over from the stock. Yes, I now regret allowing that to happen. The bike is a 2009 and I bought it a year and a half ago with 495 miles on it. I was excited and chose to over look the turn signal issue not knowing it would become an issue.

    Instead of just replacing the one $32 part he had all four replaced instead or did he just throw the parts at you?

    I would have just ordered the one OEM and eaten the $32 if I were the dealer. It is not custom to just the MP3 and used on other Vespa scooters:
