Got a set of flush mount LED indicators for my CBR 600 rr and spent yesterday evening fitting them on. Got up early today to sort the wiring - All done so thought I'd test them before putting the fairing back on. For some reason when the left or right indicators are turned on independently they flash too fast since putting the LED ones on. However when the hazard switch is put on they flash all together at the right rate. I'm not much good with bike electrics - Anyone know if I've done something obviously wrong?

Oh and the wires are the right way round as they would only work one way. I'm wondering if its because they are LED on the front but currently standard on the rear?

Any advice would be great - Desperate to get out on a ride today!!

In my experience...when indicators flash too fast it is usually a `bad` earth...but you may be on to something with the mis-matched rear indicators...wiggle some wires while they are flashing to see if there is any change perhaps.....?
You might need to match the rears with LED`s...perhaps the resistance of the light is different...using less power...but I`d still consider the bike `ridable` for today unless there like strobe lights...

Hopefully someone with more experience will be along shortly, but I think you may need something like this :

Did you get some resistors with the LED lights. They need to be fitted to get the correct flash rate (or use the fancy box). The flasher relay is designed to work with a certain power output, P=I*V and V=I*R. You've changed that as the LED lights are no doubt a lower power output. The resistors bring it back to normal.

Or something like that anyway.

Got them from ebay so just got the indicators themselves - No resistors. Need to get some by the looks of it though doubt I'll find any today. Still can't understand why it makes the rears flash at the same rate unless they are designed to operate at the same speed as the front.

Thanks for all your help.

This from 'Custom Dynamics' re their 'Load Equalizer' www.customdynamics.com/ducati_led_tail_light.htm

"Stock flasher relays on motorcycles are designed to blink twice as fast as normal when a bulb is burned out. Leds consume so little power compared to the stock bulbs, that the flasher relay thinks that a bulb is burned out when this is not the case. If you have replaced your stock turn signals with LEDs and your turns signals flash too fast or do not flash at all, you may need to add a universal load equalizer. The Fast Flash will not harm the bike, some people believe the fast flash draws more attention, if you like the faster flash rate this part is not needed.
Universal Turn Signal Load Equalizer w/ connectors
Simple locate the turn signal wires and snap into place with the supplied connectors. The load equalizer produces and equivalent load of 7.5 ohms, therefore the unit will get hot. Caution: This load equalizer will get hot, please mount accordingly. Suggesting Mounting - Under seat securely mounted to frame rail."


Basically it's just resistors in a package but that's what you need.......

There's one ever-so-slight niggle with the 'fast flash' suggestion: IIRC Construction & Use regs state that the indicators must flash between 60 and 120 times a minute. In theory if the fast flash exceeded this it could be construed as a breach of C&U, but I doubt you'd find a copper who could be arsed... scratchchin then again...

Well I bought an aftermarket relay (Supposedly honda specific)which is supposed to cure the problem. Haynes manual say's the original is between the headlights so took the fairing off find a relay between the headlights but too many wires coming out of it so reckon this is the headlight relay although they could be a combined relay unit? Anyway wouldn't have worked so put the bike back together and will use it tomorrow with my fast flash!!

Will need to look at it again when I've got more time. Does anyone know if the flasher unit is located elsewhere on the bike - Looked everywhere but couldn't see it so can only assume its the unit between the headlight. Looks like i'll be one of these resistor units then!

Sorry about hijacking the thread but you guys are talking about fast flashing... I noticed something weird on my bike today. Ignition on, all indicators flash at the standard rate. Engine running, the right hand side ones flash faster than the left hand side ones... All bulbs are good and they are standard indicators.
Any ideas?

Could be one bulb has the wrong wattage rating...
