Vespa Tail lights

[megabass]

I have a Vespa 50 S (V5SA1T) with troublesome light issues.
I cannot get the tail light to be any dimmer than a nuclear explosion.

It is always so bright that the Brake light cannot be distinguished through the glare!!

I have tried various wattage combinations. The wiring diagrams say it should have a 6V 15W bulb for the brake and a 6V 10W bulb for the tail light??

Any ideas?

Thanks

I would suggest you have the wires round the wrong way, ie; when the lights are on the brake light is operating, brake light is in fact the tail light. Change the wires round. (not the earth obviously)

I've had a look at the wiring diagram and unless your stator is kicking out 12V you must have the brake and Tail lights mixed up. The tail light should be the lower of the two bulbs (it also has to light the number plate) and should have a grey wire going to it. The upper bulb should have a blue wire. The easy way to test lights without gassing yourself in the garage is to attach a battery charger (6V in your case) to you circuit via the rectifier. If you want in depth details on how to do that just ask.

Ok

Ive checked that the bulbs are not wired up wrong and they are not.

Ive tried a 5W in the tail light with a 10W in the brake and the tail light bulb just blew!!

Im really confused!!

Any other ideas? - the brake light is nice and bright with a 10W bulb.

LED tail light??

HELP!!!

ok what is the voltage at the tail light? Get a meter and put the reed lead to the tail light terminal (where it would touch the bulb base) and the other to earth (any exposed metal attached to the frame) If you don't get a reading then try it in both AC and DC modes. Bulbs usually blow when they get too much voltage, usually caused by a faulty regulator, of course if you put a higher wattage bulb in then it will be very bright.
