Flasher Relay on a MK II ?
« on: 29 August, 2020, 09:21:42 PM »
Bike: 2011 CBF1000A (MKII)

Situation: I dislike the rear turn signals, they look terrible. I found a set of LED rear turn signals I really like online.

Question: Do I need an LED flasher relay for this bike?

Yes, the flasher rely flashers according to the combined wattage of the bulbs,  fitting LED's reduces that wattage to the extent that the indicators rapid flash or don't flash. Have you ever seen indicators flashing really fast due to one of the bulbs having blown? It's the same thing.

Hi Art,

It shows this bike has a 4 pin relay but most I see on ebay and such are two pins ones. I have load resistors in the tool box however, but a simple plug in play flasher would be better?

So it isn't an CBF1000A but a CBF1000F.
I knew that was wrong because the mkI has such cool rear indicators and it is a shame they changed that.

You need a led flasher relay replacement.  Honda, 4-pin (brand, not manufacturer).

2-pins ones are no good, you'd need a 3-pin minimum (earth ref), the right 4-pin will be a one-for-one replacement in mounting as well as plug.

You may loose the ability to lock-on your hazards (and remove your key using aftermarket relays) but as 4x 21W is too much for long without the engine running it is no real loss (but a shame as 4x leds consume less and that might actually work).

Only get led indies that are brighter than the orginal bulbs (difficult but feasible) or you may as well not bother.

Oh, and if you replace them altogether I believe you'll have bolt sizing issues (I retained my indi bodies changing the bulbs for special leds).
Only do it right - no bodging please.   Keeper of the failed stator list.   John.

Hi Sc0rch, I did this change to my Mk1 a few months back and did a post about it in another thread: see link https://www.cbf1000.com/index.php/topic,22342.0.html

The standard relay on a mk1 is a Mitsuba FR33-025 Its likely the mk2 uses the same from what I've seen but still worth checking. In any case there is a link to a relay in the other post and it's worked fine on my bike which passed its MOT a week ago with LED bulbs. I couldn't find one which had a click if you manage it would be good to know where you got it from.

I'm not sure if it's a UK vs Canada thing, but when I opened this bike up to change out the signal lights, it reveals that this bike has a 2 pin flasher relay, NOT a 4 pin.  :232:

My Lesson Learned : remove old part FIRST before buying a $60 part (incl shipping) that doesn't fit,  so I know exactly what part to get next time.

It was my blessing and curse that I ordered some resistors with my new tail signals, but it's working now until I get the right relay, or.... I just may say screw it and leave it as is now.

oh, these are the signals I bought, they look great on my bike, and brighter than stock even in day light.
