Ok, sorry to invade you all (I used to have an '01 TDR 125 by the way) but I'm having a minor electrical problem with my bike... I've just fitted a set of twin round headlights to my Kawa ER6N to replace the standard unit and for some reason the blue main beam warning light is now partially illuminated all the time when the dipped lights are on. It fully comes on when I actually switch to main beam but having it half on all th time is rather annoying!
I think the problem must stem from the fact that in the original unit the dipped headlight was a single 55W bulb and the main beam was also a single 55W bulb but reflected differently. The new units have two 60/55W bulbs which BOTH illuminate for either the dipped (55W x 2) or main beam (60W x 2).
Does anyone know how I can get round this problem without changing the bulbs or going back to the old headlight?!
Many thanks,
Dave
For anyone who's interested, here's a pic of my new beast. Slightly more rapid than the TDR!!

Nice beastie Wouldnt mind something like that myself as there are far toooo many GS1200s on the roads today and i want something a little unusual
Back to the headlights.....Having 2 bulbs with 4 fillaments rather than 2 bulbs with 2 fillaments shouldnt make much difference and should work as normal. Sounds like you might have a crossed wire somewhere on the lighting circuit. How did you wire up the dual headlight to the existing wiring?
Basically, the original unit had two 3 pin plugs with only two wires in each (12V and earth I guess?!). The twin unit came with a single 3 pin male plug on it with what I believe to be a shared earth in the top pin and the low beam and main beam taking up the other two pins. All the wiring then goes to one or the other light units with a few crossovers to make both bulbs work at the same time. This all means that I had one earth wire from the original unit spare which I've wrapped in insulating tape and left free. I've got the main beam and low beam the right way round but still have issues with the warning light.
Cheers,
Dave
P.S. I was actually tempted to specifically ask you, r0bsk1, in the title... I knew you'd be able to help!!
First thought is try connecting the spare earth to the earth that is being used as this circuit may contain the warning light.
As the high/low beams are working normaly on the switch i doubt its a problem with the internal wiring of the light unit but it should be easy enough to check. It should be a simple Y splitter so should be 6 wires......3 to each bulb (earth high low) and paired up going to the one main connector that you connect to your existing wiring
I've just tried changing the earth that's connected to the new lights (the spare one that was left hanging) and it makes no difference to my warning light dilemma
I tried both earths before (bodging with a bit of wire) and it did the same thing. When the lights are completely disconnected the warning light works as it should, off when dipped and full lit when the switch is flicked.
Just been looking at the service manual and it says there's a 'headlight relay' in the circuit. Could it be that by having two bulbs drawing current when dipped, this is just tripping the relay which is turning the blue light on? I thought that relays were either off or on with no in between but don't really know!
You're right. Relays are on or off, there's no inbetween. Headlight bulbs take a lot of juice so rather than having heavy gauge wiring throughout the whole bike, its just ran from the battery to relay and then the bulb. The wiring to the switch is light duty stuff
