Problem I have is the connector is 8 pin and no idea which pin to connect where. Couldn't find a 2018 wiring diagram via search engine so I have emailed Stanley in Japan to see if they can help with the connections.
So far the LED fits the old style headlight case perfectly and all the clips and screws line up.
Can't find the connector plug so ordered the nearest thing to it (Sumitomo TS-025" 8 way) the tiny pins maybe useful if nothing else.
Some of the pins maybe unused by Honda i.e. parking light which I think is half the DLR's at half brightness?
Anyone out there with anything to add would be appreciated. I'll keep the forum updated as/when or IF I succeed.Thanks

Sorry, can't help with the pinout.

However, I can tell you that, at least in European models, there is no parking light nor DLR. Just low beam and high beam, being the low beam always on (has to, by regulation) since you turn the key.

Unless a better idea comes your way my best suggestion is to get a proper connector for the headlight, you need a good one anyway and the next step is to test the individual led's and see which belongs in the high and low beam category, best way is to use a 12v lightbulb ( in case you accidentally make a short it will limit the current to a safe level ) in series with a 12v source and discover the pattern and polarity of the led's.

My guess is that the contacts are split into four groups, positives on one side ( top ) and the negative on the other ( lower ) that may or may not have the negative in common ( connected together ) .

You will end up with two sets of led's and the multitude of contacts is for good distribution of the load current i guess.

Next trick is to find a good way to connect the halogen connectors to the new wiring in such a way that the situation can be reversed in the future, maybe an old halogen lamp base with the glass removed can be used to solder the new wires in the right way to this base?
I have tried a 9V battery with 1K ohm resistor in line on various pins. All I managed to light was half the halo LED's. Presume it needs much more current to light the rest. I'm too nervous to give it more voltage/current. I just don't know if there is any sensitive driver electronics within the lamp housing. Toyota & Honda car LED conversions are really simple to connect up, but the documention on their 8 pin connectors is more readily available. As a last resort I could attempt dismantling the headlight and noting which pin goes where.

I presume the halo of small LED's is also on all the time for Europe. I suppose the multi-functions available are to meet many different countries regulations around the World.


RE: LED upgrade - max - 06-17-2018

The bigger led's are probably composed with 3 dies per chip in series ( 3x 3.2v ) and need 10.8 volts to even start to light up.
There are 2 voltages on the headlight body; 13.2v and 13.6 volts which seem to be the min and max operating voltage, 9 volts is just too small to light the chip, but it may actually be that the unit requires a driver unit since the system voltage can be as much as 14 volts which could spell the end of the led's, so we need more confirmation from other members which have the led light and have had a look inside their head light bucket.

Good of you to be careful; max

Good advice. Research shows the LED bike has a different part number for the regulator. It may just be an update to MOSFET type? I wonder if the lefthand handlebar switch assembly has the headlight connector attached? Again it has an updated part number.
