By changing the bulbs, you have changed the load resistance on the flasher unit. You Fat Boy does not use a flasher like a car does. It has an electronic turn signal canceller on it, a "black box". To solve your problems, you need a "load equalizer" installed in the wiring harness of your bike. There are several types of units on the market. Badlands makes a good one.

Ride Safe.

Honda cbr indicators all flashing


Hi, led bulbs have much lower power consumption than common bulbs. Usualy when you change for this type of bulbs you also need an apropriate flasher wich you did, but question the suplier about it. another solution is to instar a resistance just before the bulb in order to increase ohms ans all be normal again.
good luck

Hiya iv got a honda c90 and iv changed the back indicators to non led the old ones where 12v 10w bulbs iv now put 12v 25w bulbs, they flash to fast. how do i over come this?


hi, changing the flasher relay for a 12volt 2x24 unit will overcome this, you should be able to pick one of these up aftermarket, however i would probably try find a original equiptment unit as they sseem to be better quality, something like a cb250n, or 125tdc would have the correct 1,paul

Honda VT500EF, 1983-1988, flasher unit wiring.


The flasher unit is made to flash 12 volts on and off only. The turn signal switch is what is used to direct that flashing 12 volts to the proper signals.
The flasher unit:
First wire is a ground. Middle wire is the send to the turn signal switch. The last wire is 12v positive (with key on). When you flip the switch to the left, it makes a connection between the left turn signals and the middle wire of the flasher unit. The flasher unit then "sees' a load and starts flashing 12v on and off at the middle wire. When you flip the switch right, it makes the connection between the right signals and the middle wire of the flasher unit. Again, the flasher unit "sees" a load and starts flashing.
