    Buy another horn and put the 2 in series, especially if you can get a 2nd one with a different tone/frequency.
    or
    what current does the horn take?
    If about 2 amp's or 12 Watt's (at 6VDC) then put a 21W indicator bulb in series with it.

    to do this, your saying but the bulb in series before the horn ?

    so it would be...

    battary + ... bulb... bulb.... then horn... then back tothe battery -terminal ??

    Dont really see much point in having a horn that plays 18 different tunes

    It would be battery + then bulb.... then horn... then back to the battery -terminal ??

    Do the instructions say how much current it takes or what size is the fuse on/in it??

    It is also important to know is it requires a perminent Live supply as well.
    Perhaps a link to a website??

    The bulb will work until it blows and then no horn, yes you know to replace it but a simpler solution would be if you brought 2 resistors from Maplins at 2 kilo ohms each it will give a current flow of approx 3 amps and simply tap off from the centre tap and the grounded side. All the electronics can be enclosed in a small plastic enclosure.

    nice one guys.

    no real instuctions or power readings just say 6v power supply thats all.

    its got a perminant +power supply and negative, then a blue wire which it says connect to the horn button on the steering..... ( im guessing that is also a + terminal ?? )
